Correct option is D
Let the son's current age be x
The mother’s current age is 38 years.
The mother tells her son that when he was born, her age was the same as his current age.
This implies that the difference between their ages is equal to the son’s current age:
38 – x = x.
38=2x
⟹x= 19
So, the son's current age is x = 19 years.
The son's age 5 years from now will be: 19+5=24.
Correct answer is (d) 24 years.
