Water is pouring into a tank at constant rate. When the tank is full, 10 pumps of equal capacity empty a the tank in 12 hrs, while 15 pumps of the same capacity empty the tank in 6 hrs. The time which 25 pumps of the same capacity take to empty the tank, if the tank is full, will be: (All the pipes in pouring water into the tank are always open a. 3 hrs b. 2 hrs c. 4 hrs d. 3 hrs
