What is the value of 5x/yz? (1) xyz = 40 (2) yz/x=10 [#permalink] New post 21 Mar 2006, 17:33
What is the value of 5x/yz?

(1) xyz = 40

(2) yz/x=10


Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

EACH statement ALONE is sufficient.

Statements (1) and (2) TOGETHER are NOT SUFFICIENT

MY answer is A

1) xyz=40 x= 40/yz
solve for 5x/ yz ..Suff

2) yz/x=10, x=yz/10
can't solve for 5x/yz....Insuff

Please discuss this and pinpoint if i went wrong in my answer, thanks

i have to disagree and go with B

What is the value of 5x/yz?

(1) xyz = 40
i cant see how x= 40/yz is suff...sub that into the actual question and I think it ends up sqauring the denomintor



(2) yz/x=10
inverse this and you get x/yz=1/10
look at the intial question, Factor it out and it'll look like 5*(x/yz)


therefore i say B

Answer B,

(2) yz/x = 10 ---> x/yz = 1/10

Enough to obtain a value for 5 * x/yz, which is the question.

I think it's B.

Statement 1 won't give you just one value.
Statement 2 says that x/yz=1/10, so 5x/yz must be 5/10=1/2
