ATQ, Total capacity of the tank = L.C.M of 20 and 25 = 100 units. Efficiency of pipe 'A' alone = 100 ÷ 20 = 5 units/minute. Combined efficiency of pipes 'A' and 'B' = 100 ÷ 25 = 4 units/minute. Efficiency of pipe 'B' alone = 4 - 5 = -1 unit/minute (outlet). Time taken by pipe 'B' alone to empty 50% of the cistern = (100 × 0.5) ÷ 1 = 50 minutes.
