Monthly savings of X is 60% of his monthly income which
is Rs. 7500. If ratio of monthly expenditure of Y and X is 15:8 respectively and monthly savings of X is 25% more than that of Y then find monthly income of Y.Solution
Monthly savings of X = 0.60 × 7500 = Rs. 4500 Monthly expenditure of X = 7500 – 4500 = Rs. 3000 Monthly expenditure of Y = (15/8) × 3000 = Rs. 5625 Monthly savings of Y = 4500/1.25 = Rs. 3600 Monthly income of Y = 5625 + 3600 = Rs. 9225
