A cistern is normally filled in 8 hrs,but takes 2 hrs longer to fill because of a leak on its bottom,if Cistern is full ,how much time citern would empty?

• Ans=40 Hrs.
  If leakage/hour=1/x, then 1/8 -1/x= 1/10, solving 1/x=1/40
  So in 40 hours full cistern will be empty.

• the total time taken to fill is 10hrs including leakage time
  so consider the cistern empty time is x
  1/10=1/8-1-x
  1/x=1/40
  so 40hrs
