If a pipe can fill the tank within 6 hrs but due to leak it took 30 min more now if the tank was full hw much tym will it take to get empt-yed through the leak?

• work done by the leak in 1 hour=(1/6)-(2/13)=1/78
  so leak can empty the tank in 78 hours........

• total time taken to fill due to leak=6+1/2=13/2
  let it takes x hours to empty the tank
  (1/6)-(1/x)=(2/13)
  x=78/25 hours

• Let the capacity of the tank be 6 liters then efficiency is 1 liter/hr.
  If it took extra half an hour that means work done by leak in 6 hour and 30 minutes =work done by pipe in half hour.
  So, it would be 12*6.5=78 hours

• shortly
  
  (6*6.5)/0.5 = 78

• Hey guys, I was wrong last time.
  For 1 hour= 1/6+L=1/6.5.(1/1 Hour+30 mins=1.5 Hours)
  =>L=1/6-1/6.5=1/78
  So, In 78 Hours the whole tank get empty.
