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 .
