Answer:
Pipe takes 18 hrs to fill the tank and it takes 26 hrs when the leak operates.
Let's assume that the total capacity of tank is 234 liters. (LCM of 18 and 26 is 234)
The efficiency of pipe is 234/18 = 13 lts per hr.
Efficiency of pipe and the leak together is 234/26 = 9 lts per hr.
Hence the leak can empty the tank at a rate of 4 lts per hr.
Hence, the time taken by the leak to empty the full tank is 234/4 = 58.8 hrs

Answer:
tank filled in one hour =1/15
when leak is there tank filled in 1/18
amount of tank emptied in one hour=1/15-1/18
=1/90
so it will take 90 hours
