Part II: Analysis of Exam Areas
Use $100 for the normal bonus. If the annual bonus was normally $100, tripled it
is now $300. Therefore the increase, $200, must be placed over the new bonus of
$300:
$ 200
$ 300 = 2 3
2
⁄3 = 66 2
⁄3%
The correct answer is B.
Approximate
If it appears that you need to do extensive calculations to solve a problem, check
to see how far apart the choices are and then approximate. The reason for checking
the answers first is to give you a guide to see how freely you can approximate.
Samples
24. What is the value of ^. 889 # 55h/ 9.
97 to the nearest tenth?
A. 49.1
B. 17.7
C. 4.9
D. 4.63
E. .5
First underline what you are looking for: “nearest tenth.” Before starting any computations,
take a glance at the answers to see how far apart they are. Notice that
the only close choices are C and D, but D is not a possible choice because it is to
the nearest hundredth, not tenth. Some quick approximations — .889 , 1 and
9.
97 , 10 — leaves the problem in this form:
1#
55
10
= 55 10
= 55 .
The closest answer is C; therefore it is the correct answer. Notice that choices A
and E are not reasonable.
25. If 2,100 people work in a factory, and 21% of them work only the night
shift, approximately how many people work the other shifts?
54
A. 400
B. 800
C. 1,100
D. 1,600
E. 2,000
