Question
The monthly incomes of individuals 'A' and 'B' are
proportional, with 'A' earning at a ratio of 5:3 compared to 'B'. Their monthly savings follow a ratio of 3:1, with 'A' saving more than 'B'. Given that 'A' and 'B' incur monthly expenses of Rs. 8,000 and Rs. 6,000, respectively, calculate the monthly income of 'A'.Solution
Let the incomes of 'A' and 'B' be Rs. '5x' and Rs. '3x', respectively. ATQ; (5x - 8000)/(3x - 6000) = 3/1 5x - 8000 = 9x - 18000 x = 10000/4 = 2500 So, income of 'A' = 5x = 5 X 2500 = Rs. 12,500
