    Question

    Average age of 40 players in a team is 26 years. Two more

    players with ages (a + 6) and (a - 2) join, and the average age becomes 27 years. Find (a - 15).
    A 25 Correct Answer Incorrect Answer
    B 28 Correct Answer Incorrect Answer
    C 32 Correct Answer Incorrect Answer
    D 30 Correct Answer Incorrect Answer
    E 35 Correct Answer Incorrect Answer

    Solution

    42 × 27 − 40 × 26 = a + 6 + a − 2
    2a + 4 = 1134 − 1040 = 94
    2a = 90
    a = 45
    a − 15 = 45 – 15 = 30
