Question

24 workers can build a wall in 15 days. how many days will 9 workers take to build the similar wall

Answer 1

this in case of inverse variation let no. of days be y so
24×15=9×y
360÷9 =y
40=y

Answer 2

Answer:

9 workers take 40 days to build the similar wall.

Step-by-step explanation:

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

Let 9 workers take x days to build the similar wall.

$24\times 15=9\times x$

Divide both sides by 9.

$\frac{360}{9}=x$

$40=x$

The value of x is 40.

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