Answer 1

5.625 will be the answer for the 9 workers to build a similar wall

Answer 2

Answer:

9 workers take 40 days to build a similar wall.

Step-by-step explanation:

It is given that 24 workers can build a wall in 15 days.

Total work is done is

$W_1=24\times 15=360$

Let the same wall can build by 9 person in x days.

Total work is done is

$W_2=9\times x=9x$

$W_1=W_2$

$360=9x$

Divide both sides by 9.

$40=x$

Therefore, 9 workers take 40 days to build a similar wall.
