Correct Answer: 25.2 years


Solution : Given: The average age of 6 members of a family is 25 years.
The total age of 6 members of a family = 6 × 25 = 150
Age of youngest member = 4 years
Total ages of people before the birth of youngest member = 150 – 4 – (5 × 4) = 126
Required average = $\frac{126}{5}=25.2$
Hence, the correct answer is 25.2 years.
