If a pipe can fill the tank within 60% of an hour.But due to leak it takes 3 min more.Now the tank is full then how much time will it take to empty the tank throught the leak.?

• ANS-7h 48min
  EXPLANATION:60% of an hour=36min.
  if capacity of the tank is L
  then
  the pipe fills L in 36 min
  then in 1 min L/36
  and in 3 min 3*L/36=L/12
  L/12 leaks in 39 min.
  then L will leak in 12*39 min=468min=7h 48min.

• there's a formula:
  time to leak completely = ((complete time taken during fill with leak[39])*(time taken to fill without leak)) / (additional time taken to fill due to Leak[3])
  =(39*36)/3

• It will take 39 minutes, because 60% of an hour is 36 min & due to leakage it takes 3 min extra so total will be 36+3=39.
