Question

    1100 boys and 700 girls are examined in a test; 42% of

    the boys and 30% of the girls pass. The percentage of the total who failed is :
    A 58 Correct Answer Incorrect Answer
    B 62(2/3) Correct Answer Incorrect Answer
    C 64 Correct Answer Incorrect Answer
    D 67 Correct Answer Incorrect Answer

    Solution

    Total number of students = 1100 + 700 = 1800
    Number of students passed = (42% of 1100 + 30% of 700) - (462 + 210) = 672.
    Number of failues = 1800-672 = 1128.
    Percentage failure = (1128/1800) × 100 = 62(2/3)%.
