⇒ Time taken by Peeyush to complete the work = 30 × 3 = 90 days
Rate of doing work of Peeyush = 1/90
⇒ Time taken by Sanjiv to complete the work = 60 × (3/2) = 90 days
Rate of doing work of Sanjiv = 1/90
If both of them worked together
⇒ Then rate of doing work when both worked together = (1/90) + (1/90) = 2/90 = 1/45
∴ time taken to complete the work if they both worked together is 45 days.
