    The ratio of the pocket money of two persons ‘R’ and

    ‘S’ is 6:5, respectively. ‘R’ spends 60% of his pocket money while ‘S’ spends 70% of his pocket money. If the savings of ‘R’ is Rs. 90 more than that of ‘S’, then find the total pocket money of ‘R’.
    A Rs 500 Correct Answer Incorrect Answer
    B Rs 540 Correct Answer Incorrect Answer
    C Rs 580 Correct Answer Incorrect Answer
    D Rs 600 Correct Answer Incorrect Answer

    Solution

    Let the pocket money of ‘R’ and ‘S’ be Rs. 6x and Rs. 5x respectively
    (0.4 × 6x) – (0.3 × 5x) = 90
    2.4x – 1.5x = 90 → 0.9x = 90 → x = 100
    Therefore, pocket money of ‘R’ = 6x = Rs. 600
