Question
The average of 10 numbers is 7.
If each number is multiplied by 12, then the average of the new set of numbers will be?
Options: 7 8 24 19
Solution
The average of a set of numbers is found by adding all the numbers in the set and then dividing by the count of numbers in the set.
In this case, the average of the 10 numbers is 7. This means that the sum of all 10 numbers is 7 * 10 = 70.
If each number is multiplied by 12, the sum of the new set of numbers will be 70 * 12 = 840.
The average of the new set of numbers will be the sum (840) divided by the count of numbers (10), which is 840 / 10 = 84.
So, the average of the new set of numbers will be 84.
