    Solution

    ATQ, Let 'A' be Arjun's age. Arjun's sibling is 'A+5' years old. The younger sibling was born when Arjun's sibling was 6 years old. Since Arjun's sibling is 5 years older than Arjun = A+5=6 Now, solve for 'A' A =6−5 = 1 Therefore, Arjun was 1 year old when the younger sibling was born. So, when Arjun was born , mother's age = 30 years and father's age = 32 years So, the younger sibling was born, 1 year after Arjun: Mother's age = 30 + 1 = 31 years Father's age = 32 + 1 = 33 years Therefore, the ages of Arjun's parents when the younger sibling was born were Mother's age: 31 years and Father's age: 33 years
