Question
The average of ten numbers is 7. If each number is multiplied by 12, then the average of new set of numbers is:
Options :7198284
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 this case, the average of the ten numbers is 7. This means that the sum of all ten numbers is 7 * 10 = 70.
If each number is multiplied by 12, the sum of the new set of numbers is 70 * 12 = 840.
The average of the new set of numbers is then 840 / 10 = 84.
So, the average of the new set of numbers is 84.
