Solution and Explanation:

Approach Solution 1:
Apply the information in the question to the GMAT question at hand. These problems apply to numerous disciplines of mathematics. This question has to do with algebra. It is challenging to select the best option because of the way the options are presented. Candidates must be able to comprehend the appropriate approach to eliciting the desired response. Out of the five possible answers, there is only one that is correct.
My brother is two years older than I am.
When my sister was born, my father was 27 years old.
When I was born, my mother was 24 years old.
When my brother was born, my sister was five years old.
The father's and mother's ages at the time my brother was born.
Approach and exercise:
Assume I'm a certain age right now, and my brother is a+2 years older.
My mother is currently a + 24 years old.
When my brother was born, my sister was 5 years old.
My sister is therefore five years older than my brother.
Current age of my sister: a + 2 + 5 = a + 7
When my sister was born, my father was 27 years old.
My sister and father are therefore 27 years apart in age.
Current age of my father: a+7 + a+27 = a+34
Age of my parents at the time of the birth of my brother:
Age of brother = 0
Father's age = a + 34 = 32 years; a + 2= 0; a = -2
Mother's age is 22 years (a+24).
Correct option: A
