$\huge\underline\mathfrak{Question-}$

If 15 workers can build a wall in 48 hours how many workers will be required to build the same wall in 30 hours?

$\huge\underline\mathfrak{Answer-}$

Given ;-
15 Works can build a wall in 48 hours.

To find the number of workers required to build the same wall in 30 hours ;-

This is a case of inverse proportion where time is decreasing and number of workers is increasing.

So ,
Let the number of workers be "y"

Then ,

=> 15 : 48 :: y : 30

=> y = 15 × 48 / 30

=> y = 24

Therefore ,
24 workers will be required to build the same wall in 30 hours.

Answer 2

Answer:

24 workers can complete the same work in 30 hours.

Step-by-step explanation:

It is given that the 15 workers can build a wall in 48 hours.

Let x workers can complete the same work in 30 hours.

15 x 48 = 30 ×x

Divide both sides by 30.

15/48÷30 = x

24 =x

The value of x is 24.

Therefore, 24 workers can complete the same work in 30 hours.
