At a fruit stand yesterday, the price of each apple was $0.10 more than the price of each orange.
What was the total revenue from the sale of oranges at the fruit stand yesterday?
(1) The number of oranges sold at the fruit stand
yesterday was 5 more than the number of
apples.
(2) The total revenue from the sale of apples
at the fruit stand yesterday was $15.00

OA is wrong, I think!

Answer - E

Combined Statements, too, don't yield much info.

Price of Orange = x
Price of Apple = x + 0.1

Number of Orange Sold = n +5
Number of Apples Sold = n

(n) * (x + 0.1) = 15

There is two variables, but not two equations.

Thus - E

OA is wrong, I think!

Everything in cents
O - price of 1 orange
A - price of 1 apple
X - # of oranges
Y - # of apples


\(A=O+10\)
Question:(\(X*O\))?
(1) \(X=Y+5\)
(2) \(XO+YA=1500\)


E, 3 equations 4 variables

To further see this...
From (2) we get \(XO=1500-YA\)
So question becomes
Question:(\(1500-YA\))?
Substitute in A=O+10 & Y=X-5
Question:(\(1500-(X-5)(O+10)\))?

... Insufficient

What is a test set?

It's not an OA unless it's from GMAC.

you mean, the term 'OA' refers only to solutions posted by GMAC, and not from any others such as Kaplan ?

Kaplan has more 'typos' in their OA's than a monkey makes per hour typing on a microscopic keyboard.

The lack of quality and proofreading that goes into Kaplan is beyond words. And it's not funny at all either, I have had to 'rectify' some of Kaplans casualties, people who had no chance in hell of scoring above 5th percentile because Kaplan brainwashed them into blindly guessing.

STAY AWAY FROM KAPLAN / PRINCETON REVIEW / OXFORD.
