Question

If 15 men will finish the work in 12 days then how many men can finish the work in 6 days​

Answer 1

Step-by-step explanation:

30 men will fimish the work

Answer 2

Answer:

In man-days problems, involving certain number of men finishing a work in certain number of days, we should remember that number of days taken is inversely proportional to the number of men working.

Now if x and y are in inverse proportion, x1 * y1 = x2 * y2.

Here we have, x1 = 15 men, y1 = 12 days, x2 = 'x' men, y2 = 6 days

Using the inverse proportion relation, we have,

15 * 12 = 6x

or x = 180/6 = 30 men.

Therefore, 30 men can finish the work in 6 days.
