It takes 3 hours to fill a tank but due to a leakage it takes 4 hours
It takes 3 hours to fill a tank but due to a leakage it takes 4 hours. How long would the leak take to empty a full tank?
- 18 hours
- 16 hours
- 12 hours
- 10 hours
Answer
Time taken by tap to fill the tank = 3 hours
Time take by leak = x hours
Per hour : tap= 1/3, Leak = 1/x
part of the tank filled in 1 hour = 1/4 = 1/3 = 1/x
therefor, 1/x = 1/3-1/4 = 1/12
x = 1/12
The correct option is C.
