    Question

    In a factory, the ratio of number of male to female

    employees are 7: 18. If 27 male employees and 12 female employees left the factory, then the ratio becomes 1: 60, then how many employees are there in the factory initially?
    A 120 Correct Answer Incorrect Answer
    B 110 Correct Answer Incorrect Answer
    C 90 Correct Answer Incorrect Answer
    D 100 Correct Answer Incorrect Answer
    E 75 Correct Answer Incorrect Answer

    Solution

    Let number of male employees = 7x and number of female employees = 18x
    According to the question,
    (7x - 27)/(18x - 12) = 1/60
    => x = 4
    So, total employees = 7x + 18x = 25 * 4 = 100
