Question

A man spends 30% of his income in board and lodging, 25% of the remainder in other personal necessities and 20% of the rest in charity. If his income is Rs. 25000, find the amount left by him at the end.

Answer 1

Amount left after board and lodging = 25000-30% of 25000 = 25000 - 7500 = Rs. 17500/-

Amount left after personal necessities = 17500 - 25% of 17500 = 17500 - 4375 = Rs. 13125/-

Amount left after charity = 13125 - 20% of 13125 = 13125 - 2625 = Rs. 10500
