Question
There are two friends, 'C' and 'D'. Income of 'C' is Rs.
54,000. 'D' saves 25% of his income and 'C' saves 40% of his income. If savings of 'D' are Rs. 2,500 more than that of 'C', then find the difference between expenditures of 'C' and 'D'.Solution
ATQ, Let the income of 'D' be Rs. 'q'. Savings of 'C' = 0.40 X 54000 = Rs. 21,600 So, savings of 'D' = 0.25 X q = 21600 + 2500 So, q = (24100/0.25) = 96,400 Therefore, expenditure of 'D' = 0.75 X q = 0.75 X 96400 = Rs. 72,300 So, required difference = 72300 - 32400 = Rs.39,900
