Question
The ratio of A's income to savings is 25:9, and B's
expenditure is 60% of A's total income. If B's expenditure exceeds its savings by Rs. 3500, and A's income is 25% higher than B's income, find A's savings.Solution
Let the total income of A = 25x Then saving = 9x And expenditure = 16x Expenditure of B = 60% of 25x = 15x Then savings of B = 15x-3500 Total income of B = 15x+15x-3500 = 30x - 3500 Again, income of A = 125% of income of B Income of B = 25x/125 ×100 = 20x In bot the conditions income of B will remains the same 30x – 3500 = 20x X = 350 Savings of A = 9x = 3150
