      Question

      If 15 men or 10 boys can finish a task in 18 days, how

      long will it take for a team of 12 men and 15 boys to complete the same task? (Calculate approximate value)
      A 15 days Correct Answer Incorrect Answer
      B 8 days Correct Answer Incorrect Answer
      C 32 days Correct Answer Incorrect Answer
      D 21 days Correct Answer Incorrect Answer

      Solution

      According to the question,

      15M = 10B

      Or, 3M = 2B

      Therefore, (12M + 15B) = (8B + 15B) = 23B

      10 boys take 18 days to complete the work

      Therefore, time taken by 23 boys to complete the work = (10 × 18) / 23 = 7.83 days or 8 days
