7years ago,
Avg. age was 30 years. So the sun of their ages = 30X2=60 yrs.
Now,
Sum of couples age= 60+14=74
And age of child =4
Total : 78
Avg :78/3= 26

Heya☺
Here is your answer☺
Average age of the couple at time of marriage = 30 years....
Total age of the couple = 30 × 2= 60 years
Age of their daughter = 4 years
Age of couple after 7 years = 60 + 14 = 74
Average of family = 74 + 4 = 78 / 3 = 26 years
