25 men will take 48 days to complete the job.
Option d) 48 is correct.
Given :
30 men can complete a job in 40 days
To find :
The time taken by 25 men to complete the job (in days)
Solution :
30 men can complete a job in 40 days
Hence, work done by 30 men in 1 day = 1/40
Work done by 1 man in 1 day = 1/(40×30)
= 1/1200
Hence, 25 men will do 1/1200 × 25 work in 1 day
= 1/48
No.of days 25 men will take to complete the work = 48/1 = 48
Hence, 25 men will take 48 days to complete the job.
