Pipe A alone fill the tank in x hours and Pipe B alone fill the tank in (x – 7) hours. If the efficiency of pipe B is triple of pipe A and pipe A fill the tank is 50 liters per hour, then what is the capacity of the tank?
Pipe A alone fill 50 liters per hour, so Pipe B alone fill 150 liters per hour. Capacity of the tank = T => T/50 – T/150 = x – (x – 7) => 3T – T = 1050 => T = 525 liters
