    B Rs 1155 Correct Answer Incorrect Answer
    C Rs 1225 Correct Answer Incorrect Answer
    D Rs 1260 Correct Answer Incorrect Answer
    E Rs 1260 Correct Answer Incorrect Answer

    Solution

    Let the pocket money of ‘X’ and ‘Y’ be Rs. 7x and Rs. 4x respectively
    According to the question,
    (0.4 × 7x) – (0.5 × 4x) = 140
    2.8x – 2x = 140 → 0.8x = 140 → x = 175
    Therefore, pocket money of ‘X’ = 7x = Rs. 1225
