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
