Two taps are running continuously to fill a tank . The 1st tap could have filled it in 5 hours by itself and the second one by itself could have filled it in 20 hours. But the operator failed to realise tht there was a leak in the tank from the beginning which caused a delay of one hour in the filling of the tank. Find the time in which the leak would empty a filled tank.
A) 15 hours B) 20 hours C) 25 hours D) 40 hours
