Its not about the average. initially the average was 25 and after 3 years also the avg is same which means that 10 years ago they were having their first child and gave birth to the twins after 3 years which clearly tells us that the first child was 3 year old initially .

So now the present age of child will be 10+3 =13 years

The present age of the first child is 13 yrs
Explanation:
Here the average of couple is in concern. 10 years ago the
average of couple was 25. And it is said that the average
of couple remains same after having a child and twins after
3 years. Now that means, 10 years ago they were having 3
children with their first child 3 years old and twins with
0 yrs. And hence the present age of the first child is 3+10
which is 13.
