40 men can complete a work in 30 days. However, if 10 men leave the group, how many days will the group take to complete the work?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 40.
40 men can complete the work = 30 days
Total work = 40 × 30 = 1200 days
If 10 men leave the group,
Remaining men = 40 − 10 = 30 men
the number of days the new group will take to complete the work = 1200/30 = 40
