In every minute, three times as much water flows out of Tap A as Tap B into two empty containers, X and Y.
After 20 minutes, Container X is 2/5 filled with water and the height of water level in Container X is the same as that of Container Y as shown in the diagram above.
a) What is the length of the base of Container X?
b) How many litres of water can Container X hold?
50 x 45 = 2250
2250/3 = 750
750/25 = 30 cm
