It takes 32 men 15 days to build a wood workshop for the school, in how many days can 20 men build the same workshop?

It takes 20 men and 24 days to build a wood workshop for the school.

Step-by-step explanation:

Given: It takes 32 men and  15 days to build a wood workshop for the school.

Let 'd' be the number of days taken by 20 men to build the same workshop.

Also, the inverse relationship between the number of days and the number of workers. Therefore,

hence,  It takes 20 men and 24 days to build a wood workshop for the school.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
