      Question

      'Ankit', 'Manish', and 'Tarun' together can complete a work

      in 25 days. 'Ankit' and 'Manish' together can complete the same work in 75 days. 'Tarun' alone can finish the same work in how many days?
      A 45.7 days Correct Answer Incorrect Answer
      B 32 days Correct Answer Incorrect Answer
      C 37.5 days Correct Answer Incorrect Answer
      D 25 days Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the total work = 75 units (LCM of 25 and 75)

      Combined efficiency of 'Ankit' and 'Manish' = (75/75) = 1 unit/day

      Combined efficiency of 'Ankit', 'Manish', and 'Tarun' = (75/25) = 3 units/day

      Efficiency of 'Tarun' = 3 - 1 = 2 units/day

      Time taken by 'Tarun' to complete the work alone = (75/2) = 37.5 days
