    Suppose β€˜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 β€˜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) Γ— 30

    Or, 50n – 30n = 300

    Or, 20n = 300

    Therefore, n = 300 / 20 = 15
