Pipe A fills 10 liter tank at a rate of 15 liters per hour. Pipe B fills the same tank at a rate of 10 liters per hour. Pipe A runs alone for 100 minutes then the two of them together finish filling up the tank. How long does the whole operation take?

I think there was an error in the wording of the question and should be :"Pipe A runs alone for 10 minutes" because the tank will over flow before it even reaches 100 minutes.
