Question

Choose the options where the total weight equals that of an African elephant weighing 6000 kg.

• A. 60 stones of 100 kg each
• B. 15 trucks of 400 kg each
• C. 30 cars of 300 kg each
• D. 10 trunks of 60 kg each

Answer 1

Answer: (A), (B)

15 trucks of 400 kg each

Given that an African elephant weighs 6000 kg.

Weight of 60 stones of 100 kg each
= 60 × 100 kg
= 6000 kg
Weight of 15 trucks of 400 kg each
= 15 × 400 kg
= 6000 kg
Weight of 30 cars of 300 kg each
= 30 × 300 kg
= 9000 kg
Weight of 10 trunks of 60 kg each
= 10 × 60 kg
= 600 kg

So, 60 stones of 100 kg each and 15 trucks of 400 kg both weigh the same as an African elephant.
