Question
A tank is 3/4 full of water. After removing 30 litres of
water, it becomes 3/8 full. Find the full capacity of the tank.Solution
Let capacity of tank = C litres Initially water = (3/4)C After removing 30 L, water = (3/8)C So, (3/4)C − 30 = (3/8)C (3/4 − 3/8)C = 30 (6/8 − 3/8)C = 30 (3/8)C = 30 C = 30 × (8/3) = 80 litres
