They are 2015 and 2016.

divide 4031 by 2, and get rid of the decimal:
You will get 2015.
2015+2015 = 4030

Stan's, Mark's and Wayne's ages are 35 , 36 and 37 years respectively.

Explanation

Stan's, Mark's and Wayne's ages are consecutive whole numbers and Stan is the youngest and Wayne is the oldest.

So, lets assume that Stan's, Mark's and Wayne's ages are $n, n+1$ and $n+2$

Given that, the sum of their ages is 108. So, the equation will be.....

$n+(n+1)+(n+2)=108\\ \\ 3n+3=108\\ \\ 3n=108-3=105\\ \\ n=\frac{105}{3}=35$

So, Stan's age is 35 years , Mark's age is (35+1)= 36 years and Wayne's age is (35+2)= 37 years.
