33. B. II only. The arithmetic mean is the average (sum divided by number of items), or
6 + 2 + 10 + 2 + 5 = 25 divided by 5= 5.
The median is the middle number after the numbers have been ordered: 2, 2, 5, 6, 10. The
median is 5.
The mode is the most frequently appearing number: 2.
The range is the highest minus the lowest, or 10 - 2 = 8.
Therefore, only II is true: the median (5) equals the mean (5).
34. B. If you deposit 2¢, you could get 1 white and 1 red gumball. But if you deposit 3¢, you
will have to get two gumballs of the same color, either white or red. So the least amount to
ensure two of the same color is 3¢.
35. D. Starting from the lower left hand corner and simply counting the number of sides
around the outside of the shaded area gives 16 sides. Now multiply 16 # 3 = 48.

36. E. First solve the equation: q ⁄5 = 10
Multiply each side by 5.
5( q ⁄5) =5( 10)
q=
50
Therefore, q + 2 = 50 + 2 = 52
37. D. The total charges (without tax) equal $ 8, 600 + $ 1, 180 = $ 9,
780. Seven percent of
$ 9, 780 = . 07( 9,
780) , which gives an additional $684.60 added to that total, or
$ 9, 780 + $ 684.
60 = $ 10,
464.
60 .
38. D. Parallel lines are always the same distance apart. Only the figure in choice D appears to
contain two pairs of parallel lines.
39. A. Since Tom is shorter than Bob and Sid, and Sid is shorter than Frank, who is shorter
than Hal, Tom is the shortest.
