Kiran’s brother is 5 years older to her. Her father was 30 years old when Kiran’s sister was born, while her mother was 28 years old when Kiran was born. If Kiran’s sister was 2 years old when her brother was born, what was the age of their father when Kiran’s brother was born?
Answer and explanation
Correct answer A
The correct choice is: “32”
Only two facts are needed: the father was 30 when the sister was born, and the sister was 2 when the brother was born. So the brother was born 2 years after the sister, when the father was 30 + 2 = 32 years old.
The other data (Kiran is 5 years younger than her brother; the mother was 28 when Kiran was born) are not needed. For example, “37” comes from wrongly adding the 5-year gap between Kiran and her brother as well.
