If the range of the set of numbers {140, 90, 135, 110, 170, 145, x, 123, 136} is 110, which of the following could be x? Pick one
A) 40	B) 50	C) 60	D) 70	E) 80
The range of the other 8 numbers is 170-90= 
<gadget id="calculator">170-90</gadget>
<output>80</output>
80, so x must be either the smallest number or the largest number in the set.   Then x= 170-110= 
<gadget id="calculator">170-110</gadget>
<output>60</output>
60 or x= 90+110= 
<gadget id="calculator">90+110</gadget>
<output>200</output>
200   The answer is 60.
