Question 1.

For his birthday, Ajay gave 20 l 450 ml of milk to the children in an Ashramshala and 28 l 800 ml to the children in an orphanage. How much milk did Ajay donate?

Solution:

l | ml |

1 | |

2 0 + 2 8 |
4 5 0 8 0 0 |

4 9 | 2 5 0 |

450 ml + 800 ml

= 1250 ml

= 11 + 250 ml

∴ Ajay donated 49 l 250 ml milk

km | m |

1 | 1 5 7 5 |

– 1 |
7 5 0 |

0 | 8 2 5 |

750 m cannot be subtracted from 575 m. So, convert 1 km = 1000 m.

∴ 825 m remained to be cleaned

Question 3.

Question 4.

If half a litre of milk costs 22 rupees, how much will 7 litres cost?

Solution:

\(\begin{array}{l}\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1 \text { litre } \\ 22+22=₹ 44\end{array}\)

That is, 1 litre cost ₹ 44

∴ 7 litres costs 44 x 7 = ₹ 308

∴ 7 litres costs ₹ 308

Question 5.

If the speed of a motorcycle is 40 km per hour, how far will it travel in an hour and a quarter?

Solution:

Hour and quarter = 1 + \(\frac{1}{4}\) hours

= 40 km + \(\frac{1}{4}\) x 40 km

= 40 km + 10 km

= 50 km

∴ Motorcycle will travel in a hour and a quarter 50 km

Question 6.

If a man walks at a speed of 4 kmph, how long will it take him to walk 3 km?

Solution:

1 km = 1000 m

4 km in 1 hour, 4 km in 60 minutes

That is

2 km in 30 minutes

+ 1 km in 15 minutes

_______________________

3 km in 45 minutes

That is 1 km in 15 minutes Hence, 3

km in 15 x 3 = 45 min

∴ 3 km in 15 x 3 = 45 min

Question 7.

If a rickshaw travels at a speed of 30 kmph, how far will it travel in three quarters of an hour?

Solution:

30 kmph means

In 60 minutes 30 km and 30 minutes 15 km

and 15 minutes \(\frac{15}{2}=\frac{15 \times 5}{2 \times 5}=\frac{75}{10}\) = 7.5 km

∴ In 45 minutes 15 km + 7.5 km = 22.5 km

Question 8.

If a car travels 60 km in an hour, how far will it travel in

(1) 2 hours?

(2) 15 minutes?

(3) half an hour?

(4) three and a half hours?

Solution:

60 kmph

In 60 minutes 60 km

Hence, 1 minute 1 km

(1) 2 hours = 2 x 60 = 120 km

(2) In 15 minutes = 15 km

(3) In half an hour 60 ÷ 2 = 30 km

(4) In three and half hours

= 3 x 60 + 30

= 180 + 30

= 210 km

∴ (1) 120 km

(2) 15 km

(3) 30 km

(4) 210 km

m | cm |

9 9 | 1 0 0 |

1 0 0 – 8 0 |
0 0 5 0 |

1 9 | 5 0 |

Borrow l m = 100 cm
