Question

Shubham’s age today is 12 years and his father’s is 42 years. Shubham’s mother is younger than his father by 6 years. Find the ratio of Shubham’s age today to his mother’s age today.

Answer 1

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.
