If 30 men can do a job in 30 days, find what part of the job can be completed by 1 man in 1 day.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1/900
Total work = Men × Time
Total work = 30 × 30 = 900 units
Work done by 1 man in 1 day = 1 × 1 = 1 unit
so, 1/900 part of the work can be completed by 1 man in 1 day
