The mean of four positive integers is 5. The median of the four integers is 6. What is the mean of the largest and smallest of the integers? Multiple choice: 3, 4, 5, 6 and 8

4.

Step-by-step explanation:

The sum of all the integers = 4 * 5 = 20.

The median is 6 so that means that the mean of the 2 middle numbers is 6.

So the sum of the largest and smallest numbers is 20 - 12 = 8.

Therefore the mean of these 2 numbers is 4.
