Question

2 kg of sugar is placed on one pan of a weighing balance. Which of the following can be kept on the other pan so that the pans balance?

• A. 2000 g of feathers
• B. 2 kg of iron
• C. 2 kg of bricks
• D. 2000 g of silk

Answer 1

Answer: (A), (B), (C), (D)

2000 g of silk

1 kg = 1000 g
$\Rightarrow$ 2 kg = 2 × 1000 g = 2000 g

Since all the weights are equal to 2 kg = 2000 g, any of them can be kept on the other pan so that the pans balance.
