Prakash can complete a work in 20 days. In how many days will the work be completed by Rahul, if his efficiency is 25% more than that of Prakash?

1. 12 days
2. 15 days
3. 16 days
4. 18 days

Correct answer: 16 days

Solution

Prakash's rate is 1/20 work per day. Rahul's efficiency is 25% more, so his rate is 1.25 × 1/20 = 1/16 work per day. Hence Rahul completes the work in 16 days.
