If the mean of 5 men is 40 years, then their total age is 5 * 40 = 200 years.

If three of them are excluded, then the total age of the remaining two is 200 - 3 * x = 200 - 3x, where x is the age of each of the excluded men.

We know that the mean of the remaining two is 25, so their total age is 2 * 25 = 50 years.

Therefore, we can set up the equation:

200 - 3x = 50

Solving for x, we get:

x = 50

Therefore, the age of each of the excluded men is 50 years.
