Question

The ratio of age of mother and daughter is 7:2.while the age of daughter is 7 what is the age of mother

Answer 1

Let, daughter's age =d
Mother's age=m

Mother was 26 when she gave birth to her son

Daughter is 6 years elder to son

So, mother is 20 years older to daughter

Hence, m=20+d

Also,7d=3m
Hence, m=(7/3)d

Substituting in first equation we get,
(7/3)d=20+d
(4/3)d= 20
Hence, d=15
And, mother's age=35
