Question

The average of 5 numbers is 6. The average of 3 of them is 8. What is the average of the remaining two?

Answer 1

`3`

Explanation:

Given that the average of `5` numbers is `6`, their sum is `5xx6=30`.

Given that the average of the `3` selected numbers is `8`, their sum is `3xx8 = 24`.

So the remaining two numbers add up to `30-24 = 6` and their average is `6/2 = 3`
