25 workers can do a piece of work in 40 days. Find the percentage of work done by 50 workers in 5 days.

1. 20%
2. 30%
3. 25%
4. 40%

Correct answer: 25%

Solution

Total work = 25 × 40 = 1000 worker-days. Work done by 50 workers in 5 days = 50 × 5 = 250 worker-days. So the fraction completed is 250/1000 = 1/4 = 25%.
