(1) Ratio of Shubham's age today to his mother's age today.
(2) Ratio of Shubham's mother age today to his father's age today.
(3) The ratio of Shubham's age to his mother's age when Shubham was $10$ years old.

Answer 1

Shubham's age $=12\text{years}$

Father's age $=42\text{years}$

Mother is younger than father by 6 years therefore mother's age will be $(42-6)=36\text{years}$

1) Ratio $=12:36=1:3$
2) Ratio $=36:42=6:7$
As shubham's age was 10 years that means his mothers age was 34 years
3) Ratio $10:34=5:17$
