    Question

    The sum of the incomes of 'A' and 'B' is Rs. 80,000. If

    'A' spends 65% of his income while 'B' spends 75% of his income, then the savings of 'A' will be Rs. 6,400 more than that of 'B'. Find the income of 'A'.
    A Rs. 48,000 Correct Answer Incorrect Answer
    B Rs. 40,000 Correct Answer Incorrect Answer
    C Rs. 44,000 Correct Answer Incorrect Answer
    D Rs. 52,000 Correct Answer Incorrect Answer

    Solution

    Let the income of 'A' be Rs. 'x' Therefore, income of 'B' = Rs. (80000 - x) Savings of 'A' = 0.35 X x = Rs. '0.35x' Savings of 'B' = Rs. {0.25 X (80000 - x)} According to the question, 0.35x - 0.25 X (80000 - x) = 6400 Or, 0.35x - 20000 + 0.25x = 6400 Or, 0.6x = 26400 Or, x = 44000 Therefore, income of 'A' = Rs. 44,000
