Answers
Given
- The present age of Shubham is 12 years
- The present age of Shubham's father is 42 years
- Shubham's mother is younger than his father by 6 years.
( 1 ) Ratio of Shubham's age today to his mother's age today.
Shubham's present age = 12 years
His mother's present age:
= His Father's age - 6
= 42 years - 6 years
= 36 years
Ratio of their ages:
⟹ Shubham's age/His mother's age
⟹ 12 years/ 36 years
⟹ 1 : 3
(2) Ratio of Shubham's mother's age today to his father's age today
Shubham's father's age = 42 years
Shubham's mother's age:
= His Father's age - 6
= 42 years - 6 years
= 36 years
Ratio of their ages:
⟹ Shubham's father's age/Shubham's mother's age
⟹ 42 years/36 years
⟹ 7 : 6
(3)The ratio of Shubham's age to his mother's age when Shubham was 10 years old.
When Shubham was 10 years old,
Her mother's age:
= 36 years - 2 years
= 34 years
Ratio of their ages:
⟹ Shubham's age/His mother's age
⟹ 10 years/34 years
⟹ 5 : 17
