A man deposited 25% of his salary to a bank which offers
compound interest at the rate of 10% p.a. If the interest earned by him from the bank after 2 years is Rs. 3360, find the monthly expenditure of the man which is 54% of his monthly salary.Solution
Let the amount of money deposited in the bank be Rs. ‘x’. So, x × [(1.1)2 – 1] = 3360 0.21x = 3360, x = 16000 So, monthly income of man = 16000/0.25 = Rs. 64000 Required monthly expenditure of man = 54% of 64000 = Rs. 34560
