Shivansh and Prashant together can do a piece of work in 35 days. If Prashant is twice efficient than Shivansh, in how much time Prashant can complete the work alone.

Shivansh and Prashant together can do a piece of work in 35 days. If Prashant is twice efficient than Shivansh, in how much time Prashant can complete the work alone. Correct Answer 52.5 days

Let efficiency of Shivansh = 1 unit/day
Efficiency of Prashant = 2 unit/day
Total work = 35 × (1 + 2) = 105 units
∴ Time taken by Prashant to do it alone = 105/2 = 52.5 days
