Question
Pipe A and Pipe B together can fill the tank in 10
hours. The capacity of the pipe A is 30% 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 = 30/100 × Pipe B Pipe A /Pipe B = 3/10 Efficiency of pipe A = 3 units Efficiency of pipe B = 10 units Total work = 10 × (3+10) = 130 units Time taken by Pipe B to fill the tank = 130/10 = 13 hours
