    A team of 40 men is assigned to finish a project within

    24 days. They began the task simultaneously. To complete the project 6 days ahead of the planned schedule, how many additional men need to be recruited after the initial 6 days of work?
    A 20 Correct Answer Incorrect Answer
    B 18 Correct Answer Incorrect Answer
    C 16 Correct Answer Incorrect Answer
    D 24 Correct Answer Incorrect Answer
    E 12 Correct Answer Incorrect Answer

    Solution

    Total amount of work = 40 × 24 = 960 units Amount of work done by 40 men in 6 days = 40 × 6 = 240 units Let ‘x’ more men are required So, (40 + x) × 12 = 720 Or, x + 40 = 60 Or, x = 20
