a pipe can fill a tank in 15 hours. The tank develop a hole and 10% of water leaks out .
The pipe will now fill the tank in:
:
Let t = time for pipe to fill tank with leak
Let the full tank = 1
:
If the leak empties at 10% of the fill rate,
it would take 150 hrs to empty a full tank
:
- = 1
multiply by 150 to clear the denominators
10t - 1t = 150
9t = 150
t =
t = 16 hrs to fill it with the leak
