A cistern normally fills in 8hrs, but due to leakage in its base it takes two more hours for the cistern to be filled in,if the cistern is full how long will it take to be emptied through the leakage?

• 40 hours
  
  Let the cistern be emptied due to leakage in x hours
  Due to leakage cistern is filled in = 10 hours
  
  1/8 - 1/x = 1/10
  1/x = 1/8 - 1/10
  =1/40
  ===> x=40 hours
  
  To empty the cistern when it is full
  time taken = 40 hours

  let tank be empties in X hrs...
  through given info 1/8 - 1/x =1/10
  1/x=1/8 - 1/10=1/40
  so it takes 40mins to empty the tank....
