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.
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.

* the waste pipe can fill a tank with leak in 16 hrs.
Work done with leak in 1 hour = 1÷16.
,
Work done by leak in 1 hour = 1÷ 12 - 1÷16
= 4 - 3÷48
= 1÷48.
the total time taken to empty it = 48 hours.
