Question

If the weight of the bigger stone is three times that of the smaller stone. Which of the following weights can balance both the pans if added with the smaller stone ?
Weight of smaller stone = 3 kg.

• A. 6 kg
• B. 12 kg
• C. 9 kg
• D. 3 kg

Answer 1

The correct option is A 6 kg

Weight of smaller stone
= 3 kg

Weight of bigger stone
= 3 $\times$ 3 kg
= 9 kg

Weight on both the sides shoul be equal in order to balance both the pans.

9 kg = Required weight + 3 kg

Required weight
= 9 kg - 3 kg
= 6 kg
