    A team of 6 workers, each working 8 hours per day, can

    build a 200-metre-long wall in 15 days. How many workers would be needed to construct a 300-metre-long wall in 9 days if each worker only works 4 hours per day?
    A 30 Correct Answer Incorrect Answer
    B 25 Correct Answer Incorrect Answer
    C 12 Correct Answer Incorrect Answer
    D 15 Correct Answer Incorrect Answer

    Solution

    Let required number of men be тАШXтАЩ

    Using {(men ├Ч hours ├Ч days)/work} = constant

    {(6 ├Ч 8 ├Ч 15)/200} = {(X ├Ч 4 ├Ч 9)/300}

    Or, {(6 ├Ч 8 ├Ч 15 ├Ч 1.5)/36} = X

    Or, X = 30
