A group of 5 men or 12 women can complete a task in 70 days. Find the time taken by 5 men and 12 women to complete the task.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 35 Days.
1 man’s 1 day work = 1/(5 × 70) = 1/350
1 woman’s 1 day work = 1/(12 × 70) = 1/840
5 men and 12 women’s 1 day work = 5/350 + 12/840 = 1/35
Time required to complete the work = 35 days
