Answer:
2 days
Step-by-step explanation:
Understanding :
- Number of men is inversely proportional to the number of days taken to complete a job
- 6 men take 5 days to complete 1
- Now the number of men is 15
Solving :
- Rate of change of men ∝ 1/Rate of change of days
- 15/6 ∝ 1/(d/5)
- 2.5 = 5/d
- d = 2 days
12 x 10 =120
120= to 12 tens

7/8 first week
3/2 second week = 12/8 total
12/8 - 7/8 = 5/8 second week
7/8 first, 5/8 second, therefor 3/8 for the third week.
3/2 + 3/8 = total in third week
12/8 + 3/8 = 15/8 = 1 7/8 total in third week
