A) 36 B) 17 C) 25 D) 40 E) 35
I simply looked at the 3 different possible scores for each individual test: 17,36,25   We have to find the minimum range:   36-17=9   36-25= 
<gadget id="calculator">36-25</gadget>
<output>11</output>
11   25-17= 
<gadget id="calculator">25-17</gadget>
<output>8</output>
8   The find the minimum range, you have to make the set of the 5 scores as small as possible.   Which means that 4 of the 5 scores of each individual person is zero.   8*5= 
<gadget id="calculator">8*5</gadget>
<output>40</output>
40   Answer:40
<result>D</result>
