Answer:

2 days

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
