Reenu’s father was 38 years of age when she was born while her mother was 36 years old when her brother 4 years younger to her was born. What is the difference between the ages of her parents?
Note
Mother's age when Reenu's brother was born = 36 years.
Father's age when Reenu's brother was born = (38 + 4) = 42 years.
Required difference = (42 - 36) years = 6 years.
