segments remain ahead. Since the
boat’s average speed is the same
before and after buoy 10, it takes the
boat 5 3 5 = 25 minutes to travel
from buoy 10 to buoy 15.
10. The correct answer is (A). Given n
= 2, the 25th term of SetR=25n +
25 = 25(2) + 25 = 75. Given n = 2, the
24th term of Set S = n +23=2+23
= 25, and two times that 24th term is
50.
11. The correct answer is (C). There’s
no need to calculate either quantity,
and you can cancel the product st
from both columns. To make the
comparison, observe the place-value
shifts from the decimal number 9.3.
In Column A, the decimal point
shifts 3 places left (9,300) and 3
places right (.0093), so the quantity
is equivalent to (9.3)(9.3). You can
now see that Quantity B, which is
(9.3)(9.3), is the same as Quantity A.
12. The correct answer is (B). There’s
no need to calculate either quantity.
Given an area of 12,000 square feet,
the shortest possible rectangular
perimeter is achieved with a square,
in which all sides are the same
length. Column B describes a corral
with a width of 300 feet and a length

cipitous declines in the price of
BioFirm stock and CompuWin stock,
but only a modest increase in the
price of Ardent stock. During each of
these two months, the aggregate
change was clearly negative. In July,
however, a substantial price increase
in CompuWin stock more than offset
the combined decrease in the price of
the other two stocks.
15. The correct answer is (E). The
investor paid about $800 for 40
shares of Ardent stock (priced at
about $20 per share), and then sold
those 40 shares for about $2,200
(priced at about $55 per share).
Accordingly, the investor’s profit
amounted to approximately $1,400.
16. The correct answer is (B). The
area of any triangle =

height. Using 7 kilometers as the
base of the triangle in this problem,
the triangle’s height is the north-
south (vertical) distance from A to an
imaginary line extending west from
B. Given that farmhouse A is located

18. The correct answer is (A). K
percent is based on $100. Therefore,
K percent = K dollars, and Quantity
B will always be $1 less than
Quantity A.
19. The correct answer is (A). Apply
the formula for determining arith-
metic mean (called AM below), or
simple average. Letting x equal the
other number, solve for x:

30 ounces of soy sauce must be added
to achieve a mixture that includes
12% peanut sauce.
21. The correct answer is (C). x + y +
the measure of the third interior
angle (let’s call it w) = 180. Also, w +
z = 180 (because their angles
combine to form a straight line). So,
you have two equations:
x + y + w = 180 or x + y = 180 2 w
w + z = 180 or z = 180 2 w
Therefore, x + y = z (Quantity A =
Quantity B).
22. The correct answer is (D). The
centered information establishes
that Quantity B, pq, must be
negative, because the product of a
positive number and a negative
number is always negative. As for
Quantity A, try substituting some
simple numbers for p and q.Ifp =1
and q = 21, then p +
q = 0 while pq =
21, and therefore p + q . pq. But if p

question asks you to select the choice
that does NOT describe sales
totaling at least 10,000. Choice (C)
describes 1.7K + 4.9K + 2.2K = 8.8K
sales, which is less than $10,000.
Choice (A) describes 8.5K + 1.9K =
10.4K sales. Choice (B) describes
7.5K + 1.0K + 2.0 + 0.8 = 11.3K sales.
Choice (D) describes 4.9K + 5.1K =
10.0K sales. Choice (E) describes
8.5K + 4.9K = 13.4K sales.
26. The correct answer is (A). The
number of basic models was 13,800
(the sum of all numbers in the
“Basic” column). The number of
standard models sold was 29,900
(the sum of all numbers in the
“Standard” column). The difference
is 16,100. To find the average
premium paid for a standard model,
divide $41,000,000 by $16,100.
Rounding these figures to $40
million and $16,000, the quotient is
$2,500.
27. The correct answer is (D).
Without the square hole, each of the
cube’s six outer surfaces contains 9
square inches, for a total of 54
square inches of outer surface area.
The square hole reduces that total
