The average (arithmetic mean) of a list of 10 numbers is 15. if one of the numbers is removed, the average of the remaining numbers is 14. what is the number that was removed? Example
You know the average and the number of values in the list so you can figure out the sum of all the values in the list. • The difference between the sum before you remove the number and after you remove the number will give you the value of the number you removed • The sum of all the values when you start out is the average times the number of values: 10 x 15 =150 • The sum of the values after you remove a number is 9 x 14 =126 • The difference between the sums is 150 – 126= 24 • You only removed one number so that number is 24 How to Slove
