    Question

    The ratio of monthly income of 'A' to that of 'B' is

    5:9, and monthly savings of 'A' are 25% less than that of 'B'. If 'B' saves (1/3)rd of his monthly income such that his monthly expenditure is Rs. 15,000 more than that of 'A', then find the yearly income of 'A'.
    A Rs. 4,20,000 Correct Answer Incorrect Answer
    B Rs. 5,00,000 Correct Answer Incorrect Answer
    C Rs. 3,00,000 Correct Answer Incorrect Answer
    D Rs. 4,50,000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the monthly income of 'B' be Rs. 18x Therefore, monthly income of 'A' = 18x x (5/9) = Rs. 10x So, the monthly savings of 'B' = (1/3) x 18x = Rs. '6x' Monthly expenditure of 'B' = 18x - 6x = Rs. '12x' Monthly savings of 'A' = 0.75 x 6x = Rs. '4.5x' Monthly expenditure of 'A' = 10x - 4.5x = Rs. '5.5x' ATQ, 12x - 5.5x = 13000 Or, 6.5x = 13000 Or, x = 2000 So, the yearly income of 'A' = 12 x 10x = 12 x 10 x 2000 = Rs. 2,40,000.
