My brother is 3 years elder to me. My father was 28 years of age when my sister was born while my mother was 26 years of age when I was born. If my sister was 4 years of age when my brother was born, then, what was the age of my father and mother respectively when my brother was born?

When the sister was 4 years old, the brother was born, meaning the brother is 4 years younger than the sister. Since the father was 28 when the sister was born, his age when the brother was born was 28 + 4 = 32 years. The speaker is 3 years younger than the brother, and since the mother was 26 when the speaker was born, her age when the brother was born was 26 - 3 = 23 years. Therefore, the respective ages of the father and mother were 32 years and 23 years.
