Total money that Shanti has = 500*90 = Rs 45000
Cost of each pump after discount = 500 - 50 = Rs 450
Number of pumps that can be bought after discount = 45000/450 = 100 pumps
Cost of each pump after discount = 500 - 50 = Rs 450
Number of pumps that can be bought after discount = 45000/450 = 100 pumps
