25 men take 40 days to complete a piece of work.
How long will 20 men take to complete the same work?
Time taken by 25 men
= 40 days.
Time taken by 1 man
= (40×25) days
= 1000 days
Time taken by 20 men
= days
= days
= days
= 50 days
Time taken by 20 men = 50 days
20 men will take 50 days to complete the work.
Correct option = c. 50 days
