The Mathematics Section
Then get the total number of students in the class:
12 + 18 + 4 + 6 = 40
And finally set up the fraction 16/40, which reduces to 2/5. The correct answer is A.
44. How many combinations of outfits are possible if a person has 4 sports
jackets, 5 shirts, and 3 pairs of slacks?
A. 4
B. 5
C. 12
D. 60
E. 120
The correct answer is D. Because each of the 4 sports jackets may be worn with 5
different shirts, there are 20 possible combinations. These 20 combinations may
be worn with each of the 3 pairs of slacks for a total of 60 possible combinations.
Stated simply, 5# 4# 3= 60possible combinations.
Be Reasonable
Make sure that your answer is reasonable. That is, if you read it back into the
problem, does it make sense? Is it a possible answer?
Sample
45. Mo works at a diner and spends Monday and Tuesday washing dishes. On
Monday he washes 22 more dishes than he washes on Tuesday. If Mo
washed a total of 88 dishes on the two days, how many dishes did he wash
on Tuesday?
A. 22
B. 33
C. 66
D. 99
E. 110
First circle or underline “how many dishes did he wash on Tuesday.” Notice that
answer choices D and E are greater than the total for both days. Those choices are
not reasonable and can be eliminated. If you work the problem and come up with
choice C, you again have an unreasonable answer, because if Mo washes 66
dishes on Tuesday, and 22 more than the 66 on Monday, that is 88 dishes on
Monday alone, which equals the total for the two days.
