Question

    The average number of balloons distributed among five

    kids is 9. If each kid received 1 balloon more than the kid before, then find the highest number of balloons received by any kid.
    A 10 Correct Answer Incorrect Answer
    B 11 Correct Answer Incorrect Answer
    C 12 Correct Answer Incorrect Answer
    D 13 Correct Answer Incorrect Answer

    Solution

    Let the balloons received by 1st kid be ‘x’
    According to the question,
    (x + x + 1 + x + 2 + x + 3 + x + 4) = 9 × 5
    Or, 5x + 10 = 45
    Or, 5x = 35
    Or, x = 7
    Therefore, highest number of balloons received by any kid = (x + 4) = 11
