The amount ‘C’ has is equal to the average amount all four persons have. If the sum of the average amount all four have and the amount ‘A’ has is Rs. 880, then find the amount ‘B’ has.

    A 620 Correct Answer Incorrect Answer
    B 650 Correct Answer Incorrect Answer
    C 750 Correct Answer Incorrect Answer
    D 680 Correct Answer Incorrect Answer
    E 720 Correct Answer Incorrect Answer

    Solution

    Let ‘A’ has Rs. a Therefore, amount possessed by ‘D’ = Rs. 2a Amount possessed by ‘B’ = 1.125 × 2a = Rs. 2.25a Let the average amount possessed by all four be Rs. x Therefore, amount possessed by ‘B’ = Rs. x According to the question, 2.25a + 2a + a = 4x – x Or, 5.25a = 3x Or, x/a = 7/4 Therefore, a = 880 × 4/11 = Rs. 320 Amount possessed by ‘B’ = 2.25a = Rs. 720
