Please explain....


IMO the answer is 6.

Range = Highest -lowest

Current range is Holding of W - Z = (112-45) = 67.

Once Y has 24 more shares its holding is 118.

So new Range is (118-45) = 73.

Cheers

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.

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 stockes owned by Mr. Sami?

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



Within the given set of stocks the range is (Highest number of stocks - Lowest number of stocks)
= 112 - 45 = 67

Also new number of X stocks would be 36 and Y would be 118. Hence the new range is 118 - 36 = 82.

Increase in the range is 82 - 67 = 15.

Answer D.

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