A tank with a square base of side 5 m was 1/3 full of water. When another 100 cubic meters of water was poured into the tank, it became 1/2 full. Find the capacity of the tank.
Solution
1/2 capacity – 1/3 capacity = 1/6 capacity
1/6 capacity ----- 100 cubic metres
6/6 capacity ----- 6 x 100 cubic m = 600 cubic m
Answer: 600 cubic metres
