      Question

      A contractor was tasked with constructing a bridge

      within 45 days. To complete the project, he initially hired 75 workers. However, after 40 days, he discovered that only 75% of the work had been completed. How many additional workers must he hire to ensure the remaining work is finished on schedule?
      A 100 Correct Answer Incorrect Answer
      B 125 Correct Answer Incorrect Answer
      C 150 Correct Answer Incorrect Answer
      D 200 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the contractor employed ‘x’ more workers after 40 days. So according to question: (75 × 40)/0.75 = {(x + 75) × 5}/0.25 20x + 1500 = 4000 20x = 2500, x = 125 So, 125 more workers are required to complete the work on time.
