Ans:
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.

Answer / kirti
Ans=21
Explanation:
10 years ago the average of couple was 25 and their current
ave is also 25.
Total number of People=5
25*5=125
so the current total of their ages=125
and current total age of couple=25*2+10*2=70
125-70=55
So the current total of the ages of 3 children=55
age of the twins=17 each and present age of the first child=21.
