The table shows the number of shares of each of the 5 stocks owned by Mr Sami. If Mr. Sami was to sell 20 shares of Stock X and buy 24 shares of stock Y, what would be the increase in the range of the numbers of shares of the 5 stocks owned by Mr. Sami?

A. 4
B. 6
C. 9
D. 15
E. 20

Can someone please explain this in detail?
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:

D

The table shows the number of shares of each of the 5 stocks owned by Mr Sami. If Mr. Sami was to sell 20 shares of Stock X and buy 24 shares of stock Y, what would be the increase in the range of the numbers of shares of the 5 stocks owned by Mr. Sami?

A. 4
B. 6
C. 9
D. 15
E. 20


Current range = highest - lowest --->112-45 = 67

After selling 20 shares of X and buying 24 shares of Y , the new share composition will be
V = 68 No change
W= 112 No change
X= 36 (because 56-20=36)
Y =118 (because 94+24 =118)
Z = 45No change

Now new range = highest - lowest ----> 118- 36= 82

Increase = new range -old range = 82-67 = 15

Check out below :-

Range before transaction:
112-45=67
Range after transaction:
(94+24)-(56-20)=118-36=82
The difference is: 82-67=15

Original Range = 112 - 45
new Range = 118 - 36
so increase in range = 15

We recall that the formula for range is:

Range = greatest value - least value

Since the greatest number of shares is 112 and the least number of shares is 45, before selling stock X and buying stock Y, the current range is 112 - 45 = 67.

After 20 shares of stock X are sold and 24 shares of stock Y are purchased, the greatest number of shares is 94 + 24 = 118 and the least number of shares is 56 - 20 = 36. The new range would be118 - 36 = 82. Thus, the increase in the range is 82 - 67 = 15 shares.
