Part II: Analysis of Exam Areas
The first bit of information to pull out is what you’re looking for: “ratio of the volume
of alcohol to the volume of water.”
(You should have circled or underlined this information in the question.)
Rewrite the question as A (alcohol):W (water) and then put this ratio into working
form:
W A
Next, pull out the volumes of each:
A = 3 ⁄7 and W = 4 ⁄7
Now, you can figure out the answer easily by inspection or substitution using 3/7 ⁄4/7.
Invert the bottom fraction and multiply to get 3 ⁄7 × 7 ⁄4 = 3 ⁄4. The ratio of the volume
of alcohol to the volume of water is 3 to 4. The correct answer is C.
When pulling out information, actually write the numbers and/or letters to the
side of the problems to put them into a helpful form and eliminate some of the
wording.
7. Phil works for a furniture store 3 ⁄4 of the year and for a pool supply store
for 1 ⁄6 of the same year. He takes a vacation for the remainder of the year.
How much more time does he spend working for the furniture store than
for the pool supply store?
A. 1 month
B. 2 months
C. 7 months
D. 9 months
E. 11 months
First circle or underline “How much more time.” Next, pull out the information
regarding Phil’s work for the year:
furniture store 3 ⁄4 of a year is 3 ⁄4 × 12, or 9 months
pool supply store 1 ⁄6 of a year, or 2 ⁄12, which is 2 months
The difference is 9 months minus 2 months, which is 7 months. The correct answer
is C. Notice that taking a quick look at the answer choices is helpful, letting
you know that the answer is in months.
