Question
The average of six numbers is 40. If each number is increased by 10, what is the new average?A) 50B) 55C) 51D) 58
Solution
The new average would be 50. Here's why:
Step 1: Understand that the average of a set of numbers is the sum of those numbers divided by the quantity of numbers. In this case, the average of six numbers is 40, so the sum of those numbers is 40 * 6 = 240.
Step 2: If each number is increased by 10, the total increase would be 10 * 6 = 60.
Step 3: Add this increase to the original sum to get the new sum. So, 240 + 60 = 300.
Step 4: Divide the new sum by the quantity of numbers to get the new average. So, 300 / 6 = 50.
So, the answer is A) 50.
