Maharashtra State Board 11th Commerce Maths Solutions Chapter 9 Commercial Mathematics Ex 9.3

Question 1.
What would be the simple interest on an amount of ₹ 9,600 at the rate of 6% per annum after 3 years?
Solution:
Given Principal P = ₹ 9600
Rate of interest R = 6% p.a.
Number of years = T = 3
Simple Interest I = \(\frac{\text { PRT }}{100}\)
= \(\frac{9600 \times 3 \times 6}{100}\)
= 96 × 18
= 1728
∴ Simple interest after 3 years would be ₹ 1728

Question 2.
What would be the simple interest at the rate of 9\(\frac{1}{2}\)% per annum on ₹ 6,000 for 2\(\frac{1}{2}\) years?
Solution:
Rate of interest per annum R = 9\(\frac{1}{2}\)% = \(\frac{19}{2}\)%
Principal P = ₹ 6000
Duration T = 2\(\frac{1}{2}\) = \(\frac{5}{2}\) years
∴ Simple Interest, I = \(\frac{\text { PRT }}{100}\)
= 6000 × \(\frac{19}{2} \times \frac{5}{2} \times \frac{1}{100}\)
= 15 × 19 × 5
= 1425
∴ Simple interest would be ₹ 1425.

Question 3.
What would be the simple interest on ₹ 8,400 in 9 months at the rate of 8.25 percent per annum?
Solution:
Principal P = ₹ 8400
Rate of interest R = 8.25%
Duration T = 9 months = \(\frac{3}{4}\) years

∴ Simple interest would be ₹ 519.75.

Question 4.
What would be the compound interest on ₹ 4200 for 18 months at 10% per annum compounded half yearly?
Solution:
Principal P = ₹ 4200
Rate of interest R = 10%
Duration T = 18 months = 1.5 years
compounding is done half yearly

= \(\frac{4200 \times 9261}{2000}\)
= 4862.025
I = A – P
= 4862.025 – 4200
= 662.025
∴ Compound interest would be ₹ 662.025.

Question 5.
Find compound interest on ₹ 10,000 for 2 years at 8% per annum compounded half yearly.
Solution:
Principal P = ₹ 10,000
Rate of interest R = 8% p.a. compounded half yearly
Duration T = 2 years

I = A – P
= 11648.58 – 10000
= 1698.58
∴ Compound interest is ₹ 1698.58.

Question 6.
In how many years ₹ 1,00,000 will become ₹ 1,33,100 at compound interest rate of 10% per annum?
Solution:
Principal P = ₹ 1,00,000
Amount A = ₹ 1,33,100
Rate of interest R = 10% p.a.

∴ ₹ 1,00,000 will become ₹ 1,33,100 after 3 years.

Question 7.
A certain sum of money becomes three times of itself in 20 years at simple interest. In how many does it become double of itself at the same rate of simple interest?
Solution:
Given that, sum of money triples itself in 20 years
∴ P + I = 3P
∴ I = 2P
and T = 20 years
Now simple interest I = \(\frac{\text { PRT }}{100}\)
∴ 2P = \(\frac{\mathrm{P} \times \mathrm{R} \times 20}{100}\)
∴ R = 10
∴ Rate of interest = 10% per annum
The time period is to be calculated for the condition that the sum doubles itself i.e. for the condition
P + I = 2P
i.e. I = P
\(\frac{\mathrm{P} \times \mathrm{R} \times \mathrm{T}}{100}\) = P
∴ \(\frac{10 \times T}{100}\) = 1
∴ T = 10
∴ The sum will become double of itself in 10 years.

Question 8.
A person borrows 10,000 for 2 year at 4% p.a. simple interest he immediately lends it to another person at 6.5% p.a. for 2 years. Find his total gain in the transaction.
Solution:
Person borrows money at 4% per annum and lends it at 6.5% per annum.
∴ His gain is (6.5 – 4) = 2.5% on ₹ 10000 for 2 years
i.e. gain = \(\frac{1000 \times 2.5 \times 2}{100}\)
= 100 × 5
= ₹ 500
∴ The person will gain ₹ 500 in this transaction.

Question 9.
A man deposits X 200 at the end of each year in recurring account at 5% compound interest. How much will it become at the end of 3 years?
Solution:
At end of 1st year, 2nd year and 3rd year ₹ 200 were deposited.
Rate of interest R = 5% p.a.
At end of 3 years, amount
= 200 + \(200\left[1+\frac{5}{100}\right]+200\left[1+\frac{5}{100}\right]^{2}\)
= 200 [1 + 1.05 + (1.05)2]
= 200 [2.05 + 1.1025]
= 200 [3.1525]
= 630.5
At end of 3 years, the account will have a balance of ₹ 630.5.

Question 10.
A man gets a simple interest of ₹ 2,000 on a certain principal at the rate of 5% p.a. in 4 years. What compound interest will the man get on twice the principal in 2 years at the same rate.
Solution:
Let Principal amount = P
Simple Interest I = ₹ 2000
Rate of interest R = 5% p.a.
Time duration T = 4 years
I = \(\frac{\text { PRT }}{100}\)
∴ 2000 = \(\frac{\mathrm{P} \times 5 \times 4}{100}\)
∴ P = 10000
Twice the principal was invested for compound interest with the same rate of interest for 2 years.
Here, P = 2 × 10,000 = ₹ 20,000
∴ Amount received,

I = A – P = 22050 – 20000 = 2050
The man will receive ₹ 2050 as compound interest.

Question 11.
The difference between simple interest and compound interest on a certain sum of money is ₹ 32 at 8% per annum for 2 years. Find the amount.
Solution:
Compound Interest = A – P = \(\mathrm{P}\left(1+\frac{\mathrm{R}}{100}\right)^{\mathrm{T}}-\mathrm{P}\)
Simple interest = \(\frac{\text { PRT }}{100}\)
Given R = 8%, T = 2 years and
compound interest – simple interest = ₹ 32

∴ The man will receive a compound interest of ₹ 5000.

2. Answer the following questions in around 35-40 words each.

Question 1.
Explain any one example of Flashbulb memory from your life.
Answer:

• I clearly remember the day when my grandmother passed away.
• On that day, I had an omelet for breakfast and went to college around 10.30 a.m. I attended only two lectures and then received a call about this bad news. After that, my best friend accompanied me home.

Question 2.
Explain the model of working memory proposed by Baddeley.
Answer:

• Baddeley called STM a working bench of memory.
• In the working memory model given by him, a central executive is responsible for the coordination between sub-systems of the phonological loop, episodic buffer, and the visuospatial sketchpad.
• Both phonological loop and visuospatial sketchpad have two components.

Question 3.
Explain the Tip of the tongue (TOT) phenomenon with an example.
Answer:

• Sometimes, when we search through our library of experiences to retrieve information from LTM, we cannot recall it even when we have that information on the tip of the tongue.
• e.g. you want to recall the name of your cousin’s favourite clothing brand. Instead of that name, you recall all similar names.

Question 4.
Give an example of episodic memory.
Answer:

• I remember a four-day-long celebration of my sister’s wedding.
• It started with Haldi followed by Mehendi and the sangeet ceremony. After that, there was a grand wedding followed by a reception ceremony.
• I also remember all preparations, outfits that I wore, and the food that we had in those four days.

Question 5.
What is motivated forgetting?
Answer:

• Motivated forgetting is a behaviour in which people may forget unwanted memories either consciously or unconsciously.
• It is also called a conscious coping strategy but it should not be confused with defense mechanisms.
• There are two levels of motivated forgetting, viz. Repression and Thought suppression.

3. Compare and contrast.

Question 1.
STM and LTM
Answer:

• Only the significant sensory inputs enter the Short-Term Memory (STM) through maintenance rehearsal. On the other hand, some items in STM enter the Long-Term Memory (LTM) after elaborative rehearsal which makes information meaningful and connects the same with already existing information in the LTM.
• STM holds the information between 15 to 30 seconds and the capacity of STM is about seven items at a time. Conversely, once information enters LTM, it is retained more or less permanently and the amount of information stored in LTM is unlimited.

Question 2.
Implicit Memory and Explicit Memory
Answer:

• Implicit memory is the unconscious memory of skills and how we do things while explicit memory is conscious memory of facts and events.
• Implicit memory is also known as procedural memory while explicit memory is also known as declarative memory.

Question 3.
Semantic memory and Episodic memory
Answer:

• Semantic memory is a more structured record of facts, meanings, concepts, and knowledge. On the other hand, episodic memory is a memory of experiences and specific events which we recall step by step to reconstruct the actual events.
• Semantic memories have personal context which includes vocabulary, mathematics, rules of logic while episodic memory is the memory of autobiographical events with times, places, and associated emotions.

Question 4.
Storage failure and Retrieval failure
Answer:

• In case of storage, failure acquired and encoded information is not stored properly while in case of retrieval failure, problems arise while recalling the stored information for its actual use.
• Both storage failure and retrieval failure make it difficult to use the retained information in the future.

Question 5.
Recall method and Recognition method
Answer:

• The recall method involves remembering a fact, event, or object that is not currently physically present and requires the direct uncovering of information from memory, (e.g. long essay-type answers). In the recognition method, already learned material is present and the learner has to recognize it. (e.g. MCQs).
• Recognition is relatively easier than recall. So, a score of memory by recognition method is usually more than the recall method.

4. What will you do if…

Question 1.
You have to prepare a long speech covering all the activities in your college and present at the annual function
Answer:

• I will make a list of all the activities and rehearse it a number of times so as to ensure better retention.
• I may also make a note with all points in brief which I can refer to if I forget something in the middle of a speech.

Question 2.
How will you apply ‘POWER’ to prepare for the final exam of Psychology?
Answer:

• Prepare: Before starting to study, I would prepare myself for it by setting goals. I will make myself aware of why am I studying Psychology, e.g. for acquiring good marks in the final exam.
• Organize: I will organize the study material properly and make a schedule for each chapter. I will allot less time for chapters that are easy and familiar. I may study these chapters when I am a bit tired. Conversely, I will allot more hours to chapters that are unfamiliar, complicated, or technical. I will also ensure to study these complex chapters when I am fresh.
• Work: I know that I have to work hard to achieve the goal of acquiring good marks. So, I will learn with the motive to understand and remember. I will try to associate new information with something that I have already learned.
• Evaluate: I will try to evaluate my progress by solving practice papers. It will enable me to know how much I have learned and the quality of my knowledge.
• Rethink: I will reanalyze, review, question, and challenge myself. I will also rethink whether I need to change my method of studying so as to achieve the goal of acquiring good marks in the final exam.

5. Short Notes.

Question 1.
Characteristics of Memory
Answer:

• Memory is an ability by which information is encoded, stored, and retrieved when needed.
• Three basic processes or characteristics of memory are Acquisition, Storage, and Retrieval.
• The acquisition is the process of acquiring information from our sense organs. The information acquired and encoded is stored over a period of time. In retrieval, the stored information is recalled for the purpose of its actual use.
• There are three stages of memory, viz. Sensory information store, short-term memory, and long-term memory.

Question 2.
Techniques to improve memory
Answer:
Some techniques to improve memory are as follows:

• Keyword method: In the keyword method, any two different pieces of information can be linked together. It is an effective method for remembering definitions and learning foreign language vocabulary.
• Encoding specificity: According to encoding specificity, memory is improved when information is available while learning is also available at the time to recall.
• Method of loci: It involves creating an imaginary route so that things can be remembered in a better way. e.g. steps to solve mathematical problems.
• Mnemonic devices: Mnemonics will include acronyms or first letter techniques (e.g. VIBGYOR includes colours of the rainbow). It will also include visualization. Another technique is chunking where one can place large information into small chunks.
• Practice and rehearsal: Relearning the same material a number of times lead to better retention and better recall. For small size or easy material, it is effective to optimally utilize our time and learn the entire material. For large size or difficult material, we must take breaks and learn the material in parts.
• Minimizing interference: We should not learn similar subjects together as they might interfere with each other. Also, one must take a rest for minimising such interference.
• POWER method: One can also use the POWER method for improving memory. Here, P stands for Preparation, 0 stands for Organisation, W stands for Work, E stands for Evaluation and R stands for Rethinking.

Question 3.
Motivated forgetting
Answer:

• Motivated forgetting is a behaviour in which people may forget unwanted memories either consciously or unconsciously.
• It is also called a conscious coping strategy but it should not be confused with defense mechanisms.
• There are two levels of motivated forgetting, viz. Repression and Thought suppression.
• Repression: Sigmund Freud’s Psychoanalytic model states that we subconsciously push unwanted thoughts and memories into our unconsciousness. People think that such repressed memories are completely forgotten.
• e.g. a girl who had experienced sexual abuse during childhood may completely forget about it. But she may have difficulty while forming a romantic relationship.
• Thought suppression: It is a conscious effort where we forget the memories of unwanted incidents and experiences of our lives, e.g. a person will avoid talking about his breakup.
• Thought suppression can be time-consuming and also quite difficult as such suppressed thoughts tend to reoccur, e.g. a person may try to suppress the thoughts about his ex but he may not be successful in doing so.

Question 4.
Causes of forgetting
Answer:

• Trace decay: Our memories fade out when we don’t use them for a longer period, i.e., traces of memory get decayed over time if they are not used.
• Trace distortion: Some researchers believe that memory traces are not decayed but are distorted over a period of time and forgetting occurs.
• Interference: Some researchers believe that we forget when materials that we learn one after the other interfere with each other. There are two types of interference, viz. retroactive interference and proactive interference.
• Motivated forgetting: It is a behaviour in which people may forget unwanted memories either consciously or unconsciously. There are two levels of motivated forgetting, viz. Repression and Thought suppression.

6. Answer the following questions in 150-200 words.

Question 1.
Explain the process of human memory in detail.
Answer:

• Memory is an ability by which information is encoded, stored, and retrieved when needed.
• The basic processes of memory include acquisition (encoding), storage, and retrieval.
  
• Acquisition/Encoding: Acquisition is the process of acquiring information from sense organs. Encoding is the process of transforming the information received into suitable symbols like pictures, figures, words, numbers.
• Storage: The information acquired and encoded is preserved over a period of time. The process of storage is essential for using that information in the future.
• Retrieval: It is the process of recalling the stored information for the purpose of its actual use. We tend to retrieve mobile numbers, names, etc. in our daily life.
• We can think of these processes as analogous to the functions of a computer.

Question 2.
Explain the theories of forgetting in detail.
Answer:

• Forgetting is the failure to retrieve the material from our long-term memory which we had already stored.
• Researchers have put forward various theories of forgetting. Each theory highlights different reasons behind forgetting.
• The various theories of forgetting are: Trace decay theory, Trace distortion theory, and Interference theory.
  • Trace decay: Our memories fade out when we don’t use them for a longer period, i.e., traces of memory get decayed over time if they are not used.
  • Trace distortion: Some researchers believe that memory traces are not decayed but are distorted over a period of time and forgetting occurs.
  • Interference: Some researchers believe that we forget when materials that we learn one after the other interfere with each other. There are two types of interference, viz. retroactive interference and proactive interference.

7. Arrange the following elements in concepts of memory in ascending order.

Question 1.
Elaborative rehearsal, Short Term Memory, Receiving information from the environment, Long Term Memory, Retrieval
Answer:

• Receiving information from the environment
• Short Term Memory
• Elaborative rehearsal
• Long Term Memory
• Retrieval

Activities

Activity 1 (Textbook Page No. 87)

Do you remember your first picnic at your school? Do you remember your primary school teacher? Now can you remember what food you ate last Monday? Why you can remember some incidents from the past clearly while you cannot remember some things which happened yesterday?
Answer:
We remember some incidents from the past clearly when they are a part of our long-term memory. Similarly, we cannot remember certain incidents from the recent past whey they form a part of our sensory or short-term memory.

Activity 2 (Textbook Page No. 87)

Why does this happen? 25 workers used to work in Thomas Edison’s Bulb and Phonogram unit of industries. There was a huge tree near his company. After 6 months, Edison asked his workers about the huge tree but not a single worker could give information about that tree. Why do you think this happened despite seeing the tree every day?
Answer:
I feel the none of the workers could give information about the tree near their company since it was a part of their sensory memory, i.e., they perceived the stimulus (tree) with sense organs but did not rehearse it enough for it to become a part of their long term memory.

• Occipital lobe: It is the visual processing center. It controls the sense of hearing, smell, and taste. It has Wernicke’s area which helps in language understanding.
• Temporal Lobe: Hearing, understanding language, memory for language take place because of the temporal lobe.

Question 3.
Explain the functions of the Amygdala and Hippocampus.
Answer:

• Amygdala: It stores emotional memories of experiences. We experience emotions, especially fear due to the amygdala.
• Hippocampus: It is the storage of long-term memories. If a person gets Alzheimer’s disease, his hippocampus is. mainly affected.

Question 4.
What is a synapse? How does a nerve impulse travel from one to another neuron?
Answer:

• A synapse is a gap between two neurons.
• The nerve impulse or neural message jumps across the synapse in order to reach the dendrite of another neuron.
• When the neural message is passing through, it excites or inhibits the neurotransmitter in it. This chemical reaction decides our reaction to various situations.

Question 5.
Which are the important parts of the hindbrain? Explain their functions.
Answer:
Important parts of the hindbrain and their functions are as follows:

• Cerebellum: It helps in maintaining body posture and body balance. It also helps in the coordination of the movements.
• Brain stem: Medulla oblongata controls the breathing rate, pulse rate, blood pressure, and digestion. Pons sends and receives information from the lower parts of the brain. It helps to transmit messages between the cerebellum and cortex.
• Reticular activation system: Its main function is to maintain wakefulness, concentration, and alertness.

Question 6.
How do endocrine glands affect our behaviour?
Answer:

• Endocrine glands secrete chemical substances called hormones.
• Hormones are like messengers that are responsible for certain behaviours or the absence of reactions.
• e.g. Thyroid gland secretes the thyroxin hormone. Its hypersecretion leads to Grave’s disease while hyposecretion results in cretinism or myxedema.

4. Write short notes.

Question 1.
Autonomic Nervous System
Answer:

• The autonomic nervous system controls the internal activities of the human body including heart rate, breathing, digestion, disposal of waste products, and toxins.
• It is divided into the sympathetic and parasympathetic nervous systems.
• The sympathetic nervous system prepares our body to face stressful and threatening situations. It prepares us for a ‘flight or fight reaction. The job of the system is just opposite to its name.
• The parasympathetic nervous system takes over when the situation becomes normal. It directs our body to store energy for emergencies.

Question 2.
Limbic System
Answer:
One of the important parts of the brain is the limbic system.

• Hippocampus, amygdala, thalamus, and hypothalamus are parts of the limbic system.
• Hippocampus is responsible for the storage of long-term memories.
• Amygdala stores emotional memories of our experiences.
• Thalamus is called a relay station of the brain. It receives all information from the body and sends it to various parts of the brain.
• Hypothalamus controls major bodily needs like hunger, thirst, sex as well as temperature regulation, and sleep.

Question 3.
Neurotransmitters
Answer:
Neurotransmitters are chemical messengers. The important neurotransmitters are:

• Acetylcholine: It is a chemical released by motor neurons of the nervous system to activate muscles.
• Dopamine: It is released by the brain. If the level of dopamine is normal, we experience happy, pleasant feelings. It also plays an important role in the motivational process.
• Norepinephrine: It increases the force of skeletal muscles, especially during fight or flight response.
• Serotonin: It plays a role mainly in cognition, reward, learning, and memory. It also controls wakefulness, sleep, hunger, thirst, and liking.
• Glutamate: It helps in learning, memory, and maintaining sugar levels.
• GABA (Gama Amino Butyric Acid): It is the chief inhibitory neurotransmitter i.e. its principal role is to reduce the excitability of neurons throughout the nervous system. If it is less, it leads to convulsions and we cannot control body movements.

Question 4.
Pituitary gland
Answer:

• The pituitary gland is one of the endocrine glands, i.e., glands that secrete chemical substances into the bloodstream.
• It is also called as master gland as it helps other glands to produce their secretions and secretes the majority of hormones.
• It consists of the anterior lobe and posterior lobe.
• Anterior lobe: It secretes somatotropin, growth hormone, and adrenocorticotropic hormone. It helps the growth of the body and aids the adrenal gland. The hormones secreted by this gland are also vital for the nourishment of foetus.
• Hypo or hypersecretion in the anterior lobe: Hyposecretion leads to dwarfism, wherein a person is very short (two-three feet tall). On the other hand, hypersecretion can lead to gigantism, wherein a person becomes very huge and is eight-nine feet tall. Hypersecretion can also result in acromegaly, wherein a person has the features of a chimpanzee.
• Posterior lobe: It secretes oxytocin (which creates a feeling of happiness), pituitrin (which helps smooth muscle functioning of the stomach), thyrotrophic follicle-stimulating luteinizing hormone (which helps in the nourishment of foetus), and endorphins (which help to create neurotransmitters).

5. Compare and contrast

Question 1.
Sympathetic nervous system and Parasympathetic nervous system
Answer:

• The sympathetic nervous system prepares our body to face stressful and threatening situations. It prepares us for a ‘flight or fight reaction. On the other hand, the parasympathetic nervous system takes over when the situation becomes normal,
• Example:
  • Situation: Suppose you are chased by a dog.
  • Sympathetic nervous system: Due to the functioning of this system, your heartbeat and palpitation increase. You also start to sweat.
  • Parasympathetic nervous system: When PNS takes over, your heart rate, palpitation, and sweating become normal. You regain a cool and composed state due to the functioning of this system.

Question 2.
Exocrine glands and Endocrine glands
Answer:

• Exocrine glands directly release their secretions into the organ or tissue while endocrine glands secrete chemical substances into the bloodstream.
• Exocrine glands have separate ducts for their secretion and so, they are also called duct glands, e.g. sweat glands and tear glands. On the other hand, endocrine glands are called ductless glands as they don’t have a separate duct. e.g. pituitary gland and thyroid gland.

6. Answer in 150-200 words.

Question 1.
Explain the functions of various parts of the human brain.
Answer:
The brain consists of three major parts, viz. hindbrain, midbrain, and forebrain. Its functions are as follows:
i. Hindbrain

• Cerebellum: It helps in maintaining body posture and balance as well as aids in the coordination of movements.
• Brain stem: Medulla oblongata controls the breathing rate, pulse rate, blood pressure, and digestion. Pons helps to transmit messages between the cerebellum and cortex.
• Reticular activation system: It is the ‘Alarm clock’ of the body. It maintains wakefulness, concentration, and alertness.

ii. Midbrain: It sends information to the upper part of the brain and controls eye movements.

iii. Forebrain

• Cerebrum: Cerebral cortex controls higher-order mental processes such as attention, perception, learning, memory. The surface of the cerebral cortex is divided into right and left hemispheres. Neurons from the right hemisphere control the left side of the body and vice versa. Left hemisphere controls language, spatial relation, and pattern recognition.
• Four lobes: Frontal lobe controls motor actions, thinking, memory and reasoning. The parietal lobe helps us in understanding information regarding skin. The occipital lobe controls our vision. The temporal lobe is responsible for hearing, understanding language, and memory for language.

Question 2.
Explain the significance of endocrine glands in human behaviour. State the functions of any five endocrine glands in detail.
Answer:

• Endocrine glands secrete vital chemical substances called hormones. There is a strong impact of hormones upon human behavior.
• Hormones are responsible for certain behaviours or the absence of reactions.
• Over (hyper) or under (hypo) secretion of hormones may lead to a variety of problems.
• e.g. Hypersecretion of insulin and glycogen hormones by the pancreas reduces blood sugar levels. It results in hyperglycemia, wherein a person lacks energy and motivation, may faint and go to coma. Conversely, in the case of hyposecretion, a person gets diabetes. He becomes quite hungry and feels very tired and restless. He also shows irritated behaviour and faces frequent and uncontrolled urination.

The functions of the five endocrine glands are as follows:

• Thyroid gland: It secretes thyroxin which maintains the rate of metabolism.
• Parathyroid gland: It secretes parathyroxin which maintains calcium as well as phosphate balance.
• Pancreas: It secretes insulin and glycogen that is responsible for maintaining blood sugar levels.
• Adrenal gland: Cortex secretes cortin or cortisone which maintains the level of water, sugar, and sodium. The medulla secretes adrenalin (which is associated with fear) and noradrenaline (which is associated with anger). Medulla plays important role in emotional excitement.
• Gonads (sex gland): Testes in males secrete androgen and testosterone. These hormones are responsible for secondary sex characteristics in males. Their voice becomes hoarse. They also get mustaches and beards. Ovaries in females secrete estrogen and progesterone. These hormones are responsible for secondary sex characteristics in females. As a result, feminine looks develop and menarche begins.

(b) Means of livelihood
(c) Geographical spread
(d) Evidence of cultural contact with other people.
Answer:
(a) Period: The chalcolithic settlements in Gujarat coincide with the following phases of the Harappan culture:

• Early Harappan phase (3950-2600 B.C.E.)
• Mature (urban) phase (2600-1900 B.C.E.)
• Post-Harappan phase (1900-900 B.C.E.)

(b) Means of livelihood: There are ample sources of semi-precious stones in Gujarat. Making beads of these stones was a big industry during Harappan times. The Neolithic settlements in Gujarat played a major role in procuring these stones. People residing in the neolithic settlements of Gujarat were mainly pastoral, that is people whose primary occupation was animal husbandry. Thus, making beads, animal husbandry, pottery making were some of the means of livelihood.

(c) Geographical spread: There are regional variations in the characteristics of the chalcolithic cultures of Gujarat. The chalcolithic pottery of Kutch – Saurashtra and Northern Gujarat are distinct from each other. The chalcolithic villages in Kutch-Saurashtra were abandoned by 1900 B.C.E.

(d) Evidence of cultural contact with other people: In the post-Harappan period there were two chalcolithic cultures in Gujarat. The culture in south Gujarat was known as ‘Prabhas’ culture and the one in northeastern Gujarat was known as ‘Rangpur’ culture. These cultures existed till 1800-1200 B.C.E.

Answer:
A hierarchical system where women are given a lower social status is stratification based on gender.

2. Write short notes.

Question 1.
Principles of social stratification.
Answer:

1. Stratification is social: Social stratification is not determined by biological differences but it is governed by social norms and sanctions.
2. Social stratification persists over generations : In all society’s parents confer their social status on their children. Thus, the pattern of inequality stays same from generation to generation.
3. Social stratification is universal but variable : Social stratification is found everywhere. At the same time the nature of inequality varies. ‘What’ is unequal and ‘how’ unequal, changes within the context of a society.
4. Social stratification involves inequality : Any stratified system not only gives people more resources but also justifies this arrangement and defines them as fair.
5. Social stratification is consequential : Stratification affects every aspect of life of all individuals. Social life is affected because of the position of an individual in the social hierarchy. Some experience positive consequences, while others face negative consequence of the hierarchy in a particular society.

Question 2.
Characteristics of caste according to Dr. G.S. Ghurye.
Answer:
Dr. G.S. Ghurye a well known Sociologist and Indologist defines caste in terms of its essential characteristics. They are as follows:
1.Segmental division by society : Society is divided into various castes. The membership of castes are determined by birth. Therefore, mobility from one caste to another is impossible.

2. Hierarchy: Castes or segments are arranged in terms of hierarchy. According to Dr. Ghurye, castes are graded and arranged into a hierarchy on the basis of the concept of ‘purity and pollution’.

3. Restriction on feeding and social intercourse : This fact of separation is reinforced by the notion of ‘purity and pollution’. Each caste imposes restrictions on its members with regard to food and social intercourse.

4. Differential civil and religious privileges and disabilities : In a caste society there is an unequal distribution of privileges and disabilities among its members. The higher castes enjoy all privileges and lower caste suffer from all kinds of disabilities.

5. Lack of unrestricted choice of occupation : Choice of occupation is not free under caste system. Occupations are hereditary and the members of the caste are expected to follow their traditional occupation.

6. Endogamy : Endogamy is the essence of caste system. Every caste of sub-caste insists that its member should marry within the group.

Question 3.
Types of mobility.
Answer:
1. Horizontal Mobility : It refers to change of residence or job without status change. Under this type of social mobility, a person changes one’s occupation but the overall social standing remains the same. Certain occupation like doctor, engineer and teacher may enjoy the same status but when an engineer changes one’s occupation from engineer to teaching engineering there is a horizontal shift from one occupational category to another but no change has taken place in the system of social stratification.

2. Vertical Mobility : Vertical mobility refers to any change in the occupational, economic, political status of an individual or a group which leads to change of their position. Vertical Mobility stands for change of social position, either upward or downward.

3. Intergenerational Mobility : This type of mobility means that one generation changes its social status in contrast to the previous generation. However, this mobility may be upward or downward. For e.g., people of lower caste or class may provide facilities to their children to get higher education, training and skills, with the help of which the younger generation may get employment in higher position.

4. Intragenerational Mobility : This type of mobility takes place in the lifespan of one generation. A person may start one’s career as a clerk and after acquiring more education, becomes an IFS Officer. Here the individual moves up and occupies a higher social position than previously.

Each class has a set of values, attitudes, beliefs and behaviour norms which differ from those of the other classes. A social class is essentially a status group which is achieved. Class is almost a universal phenomenon. Each social class has its own status in the society. Status is associated with prestige. A social class is relatively a stable group. Social class represent an open social system. An open class system in one in which vertical social mobility is possible.

Example : Within this system, individuals can move from one class to another through hard work, education and skills. Ownership of wealth and occupation are the chief criteria of class differences but education, hereditary, prestige, group participation, self identification and recognition by others, also play an important role in class distinction.

Gender as a form of social stratification:
Gender stratification refers to social ranking, where men typically inhabit higher statuses than women. A common general definition of gender stratification refers to the unequal distribution of wealth, power and privilege between the two sexes. Throughout the world, most societies allocate fewer resources to women than men. Almost all societies are characterized by sexism. Sexism is the belief that one sex is superior than the other. Although, societies have been believing in the superiority of men over women and therefore have been dominating women. This male dominance is supported further by patriarchy. The process of socialization is gendered and creates gender hierarchy. Example : Boys are given toy cars or lego sets or bat and ball to play whereas girls are given household sets, medical sets, dolls, etc.
