Question : The average of 10 numbers is 8. If each number is multiplied by 10, then the new average will be:
Option 1: 80
Option 2: 18
Option 3: 8
Option 4: 50
Correct Answer: 80
Solution :
When each number in a set is multiplied by a constant, the average of the set is also multiplied by that constant.

$\therefore$ The new average = 8 × 10 = 80
Hence, the correct answer is 80.
