Solution
The correct option is B 10 Given - the weight of soil taken is 50 g and the volume of water absorbed is 15 ml. But to find the percentage, we need the weight of water. It is important to know that 1 ml of water weighs 1 g. So, 15 ml of water weighs 15 g. So percentage is 1550×100 which is 30%
