    Question

    A and B have monthly incomes in the ratio of 6:5,

    respectively. Both save the same amount each month. A's monthly expenses are five times B's monthly savings. Additionally, B's monthly expenses are Rs. 3000 less than A's. Determine the monthly income of A.
    A Rs. 21000 Correct Answer Incorrect Answer
    B Rs. 24000 Correct Answer Incorrect Answer
    C Rs. 18000 Correct Answer Incorrect Answer
    D Rs. 16000 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the monthly savings of A and B be Rs. ‘x’ each. So, the monthly expenditure of A = Rs. 5x Monthly expenditure of B = Rs. (5x – 3000) According to question; (x + 5x)/(x + 5x – 3000) = 6/5 30x = 36x – 18000 6x = 18000 x = 3000 So, the monthly income of A = 6 × 3000 = Rs. 18000
