    Question

    There are 45 players in a sports camp with an average age

    of 26 years. 5 more players join, decreasing the average to 25. Find the average age of the new players.
    A 15 years Correct Answer Incorrect Answer
    B 16 years Correct Answer Incorrect Answer
    C 17 years Correct Answer Incorrect Answer
    D 18 years Correct Answer Incorrect Answer
    E 19 years Correct Answer Incorrect Answer

    Solution

    Initial sum = 45 × 26 = 1170 years
    New total = 50
    New average = 25
    New sum = 50 × 25 = 1250 years
    Sum of new = 1250 - 1170 = 80 years
    Average = 80 ÷ 5 = 16 years
