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 mother’s age today to his father’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 mother’s age today to his father’s age today

= Shubham’s mother age today : Shubham’s father age today

= 36 years : 42 years

= `36/42`

= `(36 div 6)/(42 div 6)`    (HCF of 36 and 42 = 6)

= `6/7`

= 6 : 7

Thus, the ratio of Shubham’s mother’s age today to his father’s age today is `6/7` or 6 : 7.
