Given data:

30 men can do a piece of work in 20 hours.

To find:

In how many hours will 12 men do the same work?

Step by step solution:

In both scenarios, they are talking about the same amount of work. So, let us keep the work factor constant.

If we talk about the workforce and working hours, they are inversely proportional. More the workers are, lesser the working hours needed to get the work done.

If 30 men can do a piece of work in 20 hours,

One man can do the same in 30 x 20 = 600 hours

Then, 12 men can do the same work in \frac{600}{12}  = 50 hours

Therefore, 12 men can do the same piece of work in 50 hours.
