Answer:
16 2/3 hrs
Step-by-step explanation:
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
t/15 - t/150 = 1
multiply by 150 to clear the denominators
10t - 1t = 150
9t = 150
t = 150/9
t = 16 2/3 hrs to fill it with the leak

Hey Mate Here is Your Answer
Given,
No. of Tanks = 1
let Time to fill the tanks = T = 15 hrs
Its work = t/15
Hole leaks 10% Then time to leaks all the water in tank = t = 150 hrs
Its work = t/150
T + t = 1
= t - t = 1
15 150
= 10t - t = 1
150 150
= 10t - t = 150
9t = 150
t = 150
9
t = 16 2
