Question

A pipe can fill a tank in 15 hrs.The tank develops a hole and 10%of water leaks out. The pipe will now fill the tank in _________

Answer 1

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

Answer 2

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
