Total age of five members = 120
Before 8 years, Total age of the family at the time of birth of youngest member = 120 – 40 (5*8) = 80
Average age of the family at the time of birth of youngest member = 80/4 = 20
Before 8 years, Total age of the family at the time of birth of youngest member = 120 – 40 (5*8) = 80

Given:
- The average age of a family of five members is 24.

Solution:
Step 1: Find the sum of ages of all the family members.
- The average age of the family is given as 24.
- There are 5 family members.
- So, the sum of ages of all the family members = average age * number of family members = 24 * 5 = 120.
Step 2: Find the sum of ages of all the family members at the time of birth of the youngest member.
- The present age of the youngest member is 8 years.
- So, the age of the youngest member at the time of birth is 8 - 0 = 8 years.
- The sum of ages of all the family members at the time of birth of the youngest member = sum of ages of all the family members - age of the youngest member = 120 - 8 = 112 years.
Step 3: Find the average age of the family at the time of birth of the youngest member.
- The average age of the family at the time of birth of the youngest member = sum of ages of all the family members at the time of birth of the youngest member / number of family members = 112 / 5 = 22.4.
Answer:
- The average age of the family at the time of birth of the youngest member is 22.4 years.
