Answer:
10
Explanation:
4 hours x 12 days=48 total hours worked
48 hours x 10 men=480 man/hours
1 man/480 total hours=1/480th of the work done per man per hour
8 x 6 x 1/480=1/10 work done per day
1 work / 1/10 work done per day=10 days necessary to finish the work

Given :
10 persons work 8 hours per day and complete work in 6 days.
To find :
The number of days taken to complete the same work by 5 persons working 4 hours per day.
Solution :
- 10 persons working 8hrs per day can complete the work in 6 days.
- 10 persons working 1hr per day can complete the work in (6x8)days.
- 1 person working 1hr a day can complete the work in (6x8x10)days.
- 1 person working 4hrs a day can complete the work in [(6x8x10)/4]days.
Therefore, 5 persons working 4hrs a day can complete the work in
[(6x8x10)/(4x5)]days
= (480/20)days = 24 days
5 persons working 4hrs per day will take 24 days to complete the work.
