Monthly savings of X is 66% of his monthly income which
is Rs. 8000. 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 = 0.66 × 8000 = Rs. 5280 Monthly expenditure of X = 8000 – 5280 = Rs. 2720 Monthly expenditure of Y = (15/8) × 2720 = Rs. 5100 Monthly savings of Y = 5100/1.25 = Rs. 4224 Monthly income of Y = 5100 + 4224 = Rs. 9324
