$\sf{\huge{\underline{\orange{Answer :-}}}}$

According to the question,

6 people took 9 hours to build a barn .

Time taken by 6 people to build barn = 9 hours.

Time taken by 1 people to build barn = 9/6 hours

Time taken by 12 people to build the same barn.

➝ 9/6 × 12

➝ 9 × 2

➝ 18

Time taken by 12 people to build the same barn is 18 days.
