Question

If 4 kg of weight raises the level of water in a jug by 13 cm then level of water will rise by 12 kg.

• A. 9 cm
• B. 26 cm
• C. 39 cm

Answer 1

The correct option is C 39 cm

Rise in water when 4 kg of weight is put inside the jug = 13 cm
12 kg is thrice of the 4 kg so rise in water will also be 3 times of 13 cm.
Rise in water when 12 kg of weight is put inside the jug = 13 × 3 cm = 39 cm

Thus, the level of water will rise by 39 cm when 12 kg weight is put inside the jug filled with water.
