Question

A pipe can fill a tank in 12 hours. By mistake, a waste pipe at the bottom is left opened and the tank is filled in 16 hours . If the tank is full , how much time does the waste pipe take to empty it ?​

Answer 1

Answer:

Time taken = 48 hours

Step-by-step explanation:

Given that, the pipe can fill a tank without any leak in 12 hrs.

Work done without leak in 1 hour = 1/12

Given that, the waste pipe can fill a tank with leak in 16 hrs.

Work done with leak in 1 hour = 1/16

Now,

Work done by leak in 1 hour = 1/12 - 1/16 = 4 - 3/48 = 1/48

So, the total time taken to empty it = 48 hours.

Answer 2

Answer:

THE CORRECT ANSWER IS 48
