They tell us the range of the set {150, 90, 125, 110, 170, 155, x, 100, 140} is 95. Since
the present range without is 80, x has to be either the highest or the lowest number in the
set. If x is the lowest number, it would be 170-95=75, but that’s not an option. Therefore
x has to be the highest number. 90+95=185.

First arrange known values in ascending order
The range of these values = 170 - 90 = 80

We want the range to equal 95
So, EITHER x is less than 90 OR x is greater than 170
Also, since we want the range to increase from 80 to 95, we want x to be EITHER 15 less than 90 OR 15 greater than 170

Check the answer choices....E is greater than 170
