    Question

    Suppose ‘n’ employees can process all the files in

    50 days. If 10 more employees had participated, the work would be completed in 30 days. Find the value of ‘n’.
    A 50 Correct Answer Incorrect Answer
    B 75 Correct Answer Incorrect Answer
    C 15 Correct Answer Incorrect Answer
    D 95 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Total work = 50n units

    So, 50n = (n + 10) × 30

    Or, 50n – 30n = 300

    Or, 20n = 300

    Therefore, n = 300 / 20 = 15
