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.
