18 men can complete a work in 20 days. After 10 days, 6 men leave. In how many more days will the remaining men finish the work?
Show answer & explanation
Correct answer: D
Explanation
Given:
18 men → 20 days
6 men leave after 10 days
Total work = 18 × 20 = 360
Work done in 10 days = 18 × 10 = 180
Remaining work = 360 − 180 = 180
Now remaining men = 18 − 6 = 12
Time to complete the remaining work = 180 / 12 = 15 days
