Question

If a balloon weighs 4 grams and a stone weighs 1 kilogram, then which of the following is the heaviest?

• A. 200 balloons
• B. 1 stone
• C. 2 stones
• D. 400 balloons

Answer 1

The correct option is C 2 stones

We know that 1 kilogram = 1000 grams.

Weight of 1 balloon = 4 g

Weight of 200 balloons
= 200 × Weight of 1 balloon
= 200 × 4 g
= 800 g

Weight of 400 balloons
= 400 × Weight of 1 balloon
= 400 × 4 g
= 1600 g

Weight of 2 stones
= 2 × 1000 g
= 2000 g

Therefore, 2 stones weigh more than the remaining.
