4 men can make 4 cupboards in 4 days. How many cupboards can 14 men make in 14 days?

Given:

4 men can make 4 cupboards in 4 days.
To do:
We have to find the number of  cupboards 14 men can make in 14 days.

Solution:

In this type of problems, we use unitary method.

Therefore,

Number of cupboards made by 4 men in 4 days$=4$.

Number of cupboards made by 1 man in 4 days$=\frac{4}{4}=1$

Number of cupboards made by 1 man in 1 day$=\frac{1}{4}$

Number of cupboards made by 14 men in 1 day$=14\times\frac{1}{4}=\frac{7}{2}$.

Number of cupboards made by 14 men in 14 day$=14\times\frac{7}{2}=7\times7=49$.

Therefore, 14 men can make 49 cupboards in 14 days.
