35 men can do a piece of work in 8 days. Find the time required by 16 men to do four times the work.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 70 Days.
Total work = 35 × 8 = 280 man-days
Four times of work = 4 × 280 = 1120 man-days
Time required for 16 men = 1120/16 = 70 days
