A tap can fill a tank in 16 hours .Due to a hole in its base it is filled in 24 hours .If tank is full then in how many hours it will be empty through the

hole .


As in this image I have solved the whole question considering X as water flow from tap and Y as the leakage and Z as the capacity of the tank
24X -24Y= Z
by solving these two equations we get that it will take 48 hours to empty the tank through the hole.
