The age of the father is four times that of his daughter.
f=4s
the age of the son is half of that of his mother.
b=1/2m or m=2b
brother is seven years older than his sister.
b=s+7
The wife is 8 years younger to her husband.
f=m+8 or 4s=2(s+7)+8
4s=2(s+7)+8
4s=2s+14+8
4s=2s+22
2s=22
s=11
b=18
m=36
f=44
The wife's age is 36 years old.
