Monika's father was 38 years of age when she was born and Monika's mother was 36 years old when her sister four years younger to her was born. What is the difference between the ages of her parents?
-
8 years
-
4 years
-
6 years
-
2 years
C
Correct answer
Explanation
Father was 38 when Monika was born. Mother was 36 when Monika's sister (4 years younger) was born, so mother was 36 - 4 = 32 when Monika was born. Age difference = 38 - 32 = 6 years. Option A assumes mother was 36 when Monika was born. Option B is half the correct difference. Option D assumes 2-year gap.
