which of the following could be x (GMAT-MATHS)
If the range of the set of numbers {150, 90, 125, 110, 170, 155, x, 100, 140} is 95, which of the
following could be x?
(A) 80
(B) 85
(C) 95
(D) 125
(E) 185
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
Answer: E
