Answers
Given:
Raj is 12 years old
His son was born when Raj was 9 year old
To find:
(i) Raj's age 5 years later
(ii) The sum of their ages in 5 years time.
Solution:
(i) Finding Raj's age 5 years later:
The present age of Raj = 12 years
∴ 5 years later, Raj's age will be = 12 + 5 = 17 years
Thus, Raj's age 5 years later is 17 years.
(ii) Finding the sum of their ages in 5 years time:
When Raj was 9 year old, his son was born
∴ When Raj is 12 years old i.e., after 3 years his son = 3 years
After 5 years,
Raj's age = 17 years (as calculated above)
His son's age = 3 + 5 = 8 years
∴ Sum of their ages in 5 years time = 17 + 8 = 25 years
Thus, the sum of their ages in 5 years time is 25 years.

Answer:
Step-by-step explanation:
11. (i) Raj’s age 5 years later = (12m + 5) years
(ii) Present age of Raj’s son = 12m – 9m
= 3m years
Age of Raj’s son 5 years later = (3m + 5) years
Sum of their ages in 5 years’ time = 12m + 5 + 3m + 5
= 12m + 3m + 5 + 5
= (15m + 10) years
