Question

Three men do a job in 7 days. In how many would five men do the same?

Answer 1

Answer:

Five men do the same job in 4.2 days.

Step-by-step explanation:

Let x be the time taken by 5 men.

No. of men Total time taken

3 7

5 x

Essentially, as the no.of men expands, the time taken for the work to be finished will be less as well as the other way around.

Thus, time taken is conversely relative to the no. of men.

Consequently, result of no. of men and complete time taken should be a consistent.

= (no. of men) X (absolute time taken) = consistent

= 3 × 7 = 5 × X

= X = 21/5

= X = 4.2 days.
