Answer 2

Answer:

Here's your answer.

Step-by-step explanation:

There is a formula for this.

old no of workers x days = new no of workers x days

15 x 48 = new no of workers x 30

720 = new no of workers x 30

new no of workers = 720/30 = 24

Hence 24 men are needed to complete the same work in 30 hours.
