Question
Pipe A and Pipe B together can fill the tank in 24
hours. The capacity of the pipe A is 25% of the capacity of the pipe B. How much time will pipe B alone take to fill the tank.Solution
Capacity of the pipe A = 25/100 × Pipe B Pipe A /Pipe B = 1/4 Efficiency of pipe A = 1 units Efficiency of pipe B = 4 units Total work = 24 × (1+4) = 120 units Time taken by Pipe B to fill the tank = 120/4 = 30 hours
