Question

the average of five numbers is 7, if the average of three of the numbers is 5, then what is the average of the other numbers?

Answer 1

Step-by-step explanation:

Since the average of the five numbers is 7, the total of the numbers is 5×7 = 35. When three numbers are included the average of the eight numbers is 8.5, and the sum of the numbers is 8.5×8 = 68. 68 - 35 = 33. Therefore the average of the new three numbers will be 33/3 = 11
