In a game a team receives points for three types of scores [#permalink] New post   26 Jul 2004, 07:55
In a game a team receives points for three types of scores only: 5 points, 3 points, and 1 point for scores of types X, Y, and Z, respectively. If the number of scores of type Z that the team made equaled the number of scores of type X that it made, how many scores of type X did the team make?

(1)The team received a total of 60 points.

(2)The team made twice as many types X scores as type Y scores.


Please explain. Thank you

Hey Karthik,

Thanks for reading my posts. I'm glad you're taking this to heart, because it is an important point. The two statements in a DS do have to agree.

In this case, though, I think they do. There are 3 variables, x, y, and z, and so we need to have three equations. We get one from the question: z=5x.

Statement 1 gives us another one: 5x + 3y + z = 60.
Statement 2 gives us the third: 2y = x

If you put them all together, you can solve for x (although the answer is certainly not an integer answer - but the question never said it had to be).

So I get C, also.

How did you see it?

Hi Ian,

If the answer is not an integer, is that okay?

C.

5X + 3Y + Z = Total points

1) Insufficient : 60 = 6X + 3Y

2) Insufficient: X=2Y

1+2) Sufficient.

60 = 15Y => Y=4, so X=8.

Karthik,

I wouldn't expect there to be a fractional answer, but it doesn't seem to be a problem.

Dookie, I don't read the question the way you did, but I agree that your way would make the answer an integer. But if the number of points from z equaled the number of points from x, that didn't mean that x = z, it means that 5x=z. I think we would end up with 10x, not 6x.

But either way, it doesn't matter, because it's enough info to solve the problem, integer or not.
