Given,
In order to complete a work in 28 days, 60 men are required.
To find out,
How many men will be required if the same work is to be completed in 40 days?
Explanation:
As it is given, 60 men are required to complete a work in 28 days.
That means, 60 men can complete a work in 28 days.
How many men can complete the same work in 40 days?
Solution:
Let the number of men required to finish work in 40 days be 'x'.
60 men __________ 28 days
x men ____________ 40 days
Now, it is inversely proportional.
Inversely Proportional: when one value decreases at the same rate that the other increases.
As it is inversely proportional,
28 × 60 = 40 × X
1680 = 40 × X
1680/40 = X
X = 42
Therefore 42 men are required to finish the work in 40 days.
