Question 20.

Mr. Ranjan purchased 15.500 kg rice, 25.750 kg flour and 3.250 kg sugar. Find the total weight of his purchases. Is it 50 kg or less? If less, how much less?

Solution:

Weight of rice = 15.500 kg

Weight of flour = 25.750 kg

Weight of sugar = 3.250 kg

Total weight of this purchases = 15.500 kg + 25.750 kg + 3.250 kg

= 44.500 kg

We see that the total weight of his purchases is less than 50 kg.

Thus, the total weight 44.500 kg is 5.500 kg less than 50 kg.

Question 21.

Ten years old Rahul can carry a maximum weight of 15 kg. If he bought 4 kg 900 g of apples, 2 kg 600 g of grapes and 5 kg 300 g of mangoes. Can he carry the total weight that he bought. If yes, then how much more weight he can carry with him?

Solution:

Weight of apples = 4 kg 900 g

Weight of grapes = 2 kg 600 g

Weight of mangoes = 5 kg 300 g

∴ Total weight of his purchases = 4 kg 900 g + 2 kg 600 g + 5 kg 300 g

= 4.900 kg + 2.600 kg + 5.300 kg

= 12.800 kg

But Rahul can carry a maximum weight of 15 kg.

Thus more weight that he can carry with him = 15 kg – 12.800 kg

= 2.200 kg
