If a pipe can fill the tank within 6 hours but due to leak it took 30 minutes more now if the tank was full how much time will it take to get emptied through the leak

• Let y be t time taken by leak to empty the tank
  1/6-1/y=1/6.5
  Solving we get y= 78.

• pipe can fill tank in 6 hours =6*60min=360
  due to leakage actual tym taken=360+30=390 min
  now to empty it,will be done through the leakage point which takes 30 min
  therefore390/30=13
  13*6=78(ans)
