Hi All,

This question is wordy and loaded with variables, but it can be solved by TESTing VALUES. There are some fantastic 'shortcuts' in the the answer choices as well.

We're told that there are N crates and that each crate holds Q gift boxes.

N = 3 crates

Q = 4 gift boxes/crate

(3)(4) = 12 total gift boxes

We're told that all of the crates were purchased for a total of W dollars

W = 12

12 gift boxes for 12 dollars

The seller will sell J gift boxes per 'collection' at a price of P dollars per 'collection' (we're told that J is DIVISOR of Q)

J = 2 gift boxes per 'collection'

12/2 = 6 'collections available

P = 3 dollars per 'collection'

(6)(3) = $18 in revenue after ALL collections|gift boxes are sold

Total profit is Z dollars

$18 in revenue

$12 cost

$18 - $12 = $6 = Z

We're asked for the value of P, using the other variables....

N = 3

Q = 4

W = 12

J = 2

Z = 6

We're looking for an answer that equals 3.

Now, before jumping into the answer choices, notice all of the PATTERNS that exist:

1) Answers A and B are almost exactly the same.

2) Answers C and D are almost exactly the same.

3) Each parentheses is either (Z+W) or (Z-W)

You can use the patterns to avoid doing the same calculation over and over. Let's start with Answers A and B:

A= 2(-6)/12 = -1 NOT a match

B= 2(18)/12 = 3 This IS a match

Now, let's do C and D tougher (note that we ALREADY KNOW the values of Z+W and Z-W from our prior work):

C= 4(-6)/6 = -4 NOT a match

D= 4(18)/6 = 12 NOT a match

E= 3(-6)/8 = -18/8 NOT a match

Final Answer:

GMAT assassins aren't born, they're made,
