Statement I: Pipe Q alone can fill the tank in 75 minutes Statement II: The leak can empty half of the tank in 90 minutes Statement III: Both the pipes can fill the tank in 50 minutes
The following question, there are three statements I, II and III. Read the question carefully and mark your answer according to which statements(s) is/are sufficient to the answer the question. In how much time can pipe P alone fill the tank of capacity 150 litres which has a leak at the bottom? Statement I: Pipe Q alone can fill the tank in 75 minutes Statement II: The leak can empty half of the tank in 90 minutes Statement III: Both the pipes can fill the tank in 50 minutes Correct Answer All I, II and III are together sufficient to answer
Given capacity of the tank = 150 litres
From statement I
Capacity of Q = 150/75 = 2 litre/min
From statement II
Capacity of leak = 150/(2 × 90) = (5/6)litre/min
From statement III
Total capacity (P + Q - Leak) = (150/50) = 3 litre/min
Since, capacity has been calculated; time for P can be calculated
∴ All I, II and III are together sufficient to answer
