My answer was A, but it is wrong...
Original range = (highest #) - (lowest #) = W - Z = 112 - 45 = 67;
After selling/buying: X=56-20=36 and Y=94+24=118;
New range = (new highest #) - (new lowest #) = Y - X = 118-36 = 82;
Difference = New range - Original range = 82 - 67 = 15.
Answer: D.

Hi All,
"Range" questions come from the broader category of statistics, which will show up a couple of times on the GMAT. The range of a group of numbers is the difference between the largest number and the smallest number.
Based on the original number of shares, the range would be: 112 - 45 = 67
However, the prompt tells us that two of the values in the table are going to change. After the changes, the values will be:
V 68
W 112
X 36
Y 118
Z 45
Now the range is 118 - 36 = 82
The INCREASE in the range requires us to compare the "new" range to the "old" range: 82 - 67 = 15
Final Answer:
GMAT assassins aren't born, they're made,
Rich
