Question

The initial water level was 3 cm(without any weight). The water level will be cm, if we put 3 kg weight in the jar.

• A. 6 cm
• B. 9 cm
• C. 12 cm
• D. 15 cm

Answer 1

The correct option is C 12 cm

Level of water without any weights = 3cm
Rise in water level due to 1 kg weight = 3cm + 3 cm = 6 cm
We know that higher the weight higher will be the water level
If we put 3 kg weight in the jar the rise in water level gets
double as the weight in the jar
So Total water level
= 3 cm + 3 cm + 3cm + 3 cm
= 12 cm
