Question

if 15 workers can build a wall in 48 hours, how many workers will be required to do the same work in 30 hours?​

Answer 1

Answer:

• 24 workers are the required answer.

Step-by-step explanation:

Solution:-

According to the Given Statement

→ 15 workers can build a wall in 48 hours

As we have to calculate the number of workers to do the same work in 30 hours.

Let the number of workers be n

as it is given that they are doing same work . so the required Equation is

→ 15 × 48 = n × 30

→ 720 = n × 30

→ n × 30 = 720

→ n = 720/30

→ n = 72/3

→ n = 24

• Hence, there are 24 Required to do the same work in 30 hours.

Answer 2

Answer:

Given :-

• 15 workers can build a wall in 48 hours.

To Find :-

• How many workers will be required to do the same work in 30 hours.

Solution :-

Let, the number of workers be x

According to the question,

⇒ $\sf x \times 30 =\: 15 \times 48$

⇒ $\sf x =\: \dfrac{15 \times 48}{30}$

⇒ $\sf x =\: \dfrac{48}{2}$

⇒ $\sf x =\: \dfrac{\cancel{48}}{\cancel{2}}$

➠ x = 24

Hence, the number of workers is 24.

$\therefore$ The number of workers will be required to do the same works in 30 hours is 24 .
