Correct Answer: 24


Solution : Given,
The average of 11 numbers is 8
Average = $\frac{\text{Sum of 11 numbers}}{11}$ = 8
Now, according to the question,
Every number is tripled.
We know, If each number is multiplied by a factor $n$, then the average will also be multiplied by $n$.
⇒ New average = $\frac{3\times\text{Sum of 11 numbers}}{11}$
⇒ New average = 3 × 8 = 24
Hence, the correct answer is 24.
