A street vendor sells only apples and pineapples, and all apples weigh 6.5 ounces, while all pineapples weigh 13 ounces. If she sells twice as many apples as pineapples, how many apples does she sell.

(1) She sells 8 more apples than pineapples.
(2) She sells an equal amount, by weight, of apples and pineapples.

Show Spoiler
Statement 1: a = p + 8. From the question we know that a = 2p. Substituting, we get 2p=p+8; p=8; a=16. This provides one value. Hence sufficient. Based on this the answer choice B, C, E are eliminated.
Statement 2: 6.5a = 13p; a=2p. This is the same as equation in the question [a=2p]. Since the answer choice mirrors the question, it is sufficient. The answer choice is D based on the concept above.

I formed this concept on another Veritas Prep Question provided on page 41. The solution is provided on page 45. The question is a drill.
Is 2x=3y+z
(1) \(x-z=\frac{3y}{2}\)
Solving statement 1, it becomes 2x=3y+z. According to the Veritas Prep Answer, whenever a statement exactly mirrors the question stem, it is sufficient.

Why is the Answer Choice A and not D ? Please explain.

Hi,
your statement 1 solution is perfectly fine
a = p + 8. From the question we know that a = 2p. Substituting, we get 2p=p+8; p=8; a=16.===>this is giving a definite values APPLES=16 and pineapples=8

statement 2:
6.5a = 13p; a=2p.

now here got A=2P...IN THIS A and P are variables.
you can take A=16 P=18
OR A=4 P=2...SIMILARLY MANY PAIRS CAN BE FORMED...hence the answer is not fixed...it is depending on the unknown variables A and P.

more to add...in statement 1 because of given condition that A=P+8....THIS IS ONE EQUATION
FROM QUESTION STEM WE HAVE A=2P.....THIS IS 2ND EQUATION....so we have to equation and 2 unknown.hence we can solve for a fixed value

for statement 2:
equal amount, by weight, of apples and pineapples==>this gives A=2P
FROMQUESTION STEM ===>WE HAVE A=2P......SEE HERE BOTH THE THINGS ARE GIVING SAME EQUATION N=BUT WE HAVE 2 UNKNOWN VARIABLES THAT IS WHY WE ARE UNABLE TO SOLVE BY THIS SECOND STATEMENT.

HENCE A

HOPE IT HELPS

The takeaway is that do not stop and jump to the conclusion that since the statement is mirroring the question, the answer is sufficient. Solve for the value always and make a decision after.
Thank you.

The question asks: a=? While saying that a=2p.

(2) says that a=2p. The same info as given in the stem. So, this statement is not sufficient to get the value of a.

Had the question be: is a=2p, then (2) would be sufficient.

Hope it's clear.

bb then the qn will be

A street vendor sells only apples and pineapples, and all apples weigh 6.5 ounces, while all pineapples weigh 13 ounces. Will she sell twice as many apples as pineapples?

(1) She sells 8 more apples than pineapples.
(2) She sells an equal amount, by weight, of apples and pineapples.

Answer would be B as Statement 1 is not sufficient and statement 2 is sufficient.
