Answer:

The average age of family just before tye daughter was born is 25.33 Years.

Step-by-step explanation:

we have given present age of Daughter= 8 years

Age of Mother and Daughter 4 years Back = 36 and 4 respectively, on the basis of Mother Daughter ratio of 1:9

Present age of Mother is = 40 years

Present age of Son = 15 Years

on the basis of son Mother Ratio of 33:8

Now, therefore the Age of mother and Father when son was born ( 15 years back) = 30 and 25 years.

therefore present age of father is 45 years

The age od family 8 years ago when their Daughter was born.

Father= 37

Mother= 32

Son= 7

Daughter= 0

Now, the Average age of Family

= 7+32+37/3= 25.33Years .
