x=32

Answer 2

Step-by-step explanation:

ANSWER:

Conditions are-

3 men = 8 days (3 men can complete a work in 8 days)

1 men will take more days.

So, we will take Inverse Proportion

=> 1 men will complete in 3×8=24 days.

For 12 men, it will take less time.

So, 12 men = 24/12 = 2 days.

ANSWER: 2 DAYS.
