      Question

      A team of 16 men works 9 hours a day and completes a

      task in 40 days. If the goal is to finish the same task in 30 days, with each man working 8 hours a day, how many additional workers need to be hired to meet the new deadline?
      A 8 Correct Answer Incorrect Answer
      B 24 Correct Answer Incorrect Answer
      C 10 Correct Answer Incorrect Answer
      D 12 Correct Answer Incorrect Answer

      Solution

      Let the total work be 'w' units/day Let number of men required to finish the new work be 'm' and efficiency of each man be 'e' units/hour ATQ; w/(16 x 9 x 40 x e) = w/(m x e x 8 x 30) m =  24 So, 24 - 16 = 8 additional men should be hired.
