Solution
Shubham’s age today = 12 years
Shubham’s father's age today = 42 years
∴ Shubham’s mother age today = Shubham’s father age today − 6 years
= 42 years − 6 years
= 36 years
Ratio of Shubham’s age today to his mother’s age today
= Shubham’s age today: Shubham’s mother age today
= 12 years : 36 years
= `12/36`
= `(12 div 12)/(36 div 12)` (HCF of 12 and 36 = 12)
= `1/3`
= 1 : 3
Thus, the ratio of Shubham’s age today to his mother’s age today is `1/3` or 1 : 3.
