Let the time taken by the leakage to empty the tank be X
Now
In 1hr it will fill 1/6th tank
And leakage will empty 1/X tank

Thus we can say that
1/6 - 1/X= 1/6.5
hence the value of X is 78hrs

78 hrs
xy/y-x

x = 6 hrs = 360 min
y = 6.30 hrs = 390 min

360*390/390-360
= 468 min = 468/60 = 78 hrs

Pipe takes 6 hrs to fill the thank= 6
due to leak it took 1/2 hr more = 6 and half=13/2

Work done by pipe to fill in 1 hr= 1/6
work done by leak in 1 hr = 2/13

Hence work done by leak in 1 hr = (1/6)-(2/13) =1/78
Hence it will take 78 hrs to completely empty the tank.
