Correct Answer: 11.75
Solution :
Given: The average age of 24 students is 12 years.
The sum of the age of 24 students = 24 × 12 = 288
The age of a student was taken as 14 years instead of 8 years.
So, corrected average = $\frac{(288–14+8)}{24}$
= $\frac{282}{24}$ = 11.75 years
Hence, the correct answer is 11.75.
