Quant resources - Ratio [#permalink] New post 11 Oct 2004, 06:35
Hey all,

In Quant resources on this site , here's a ratio problem and its solution :-

Quote:
If 5x = 6y and xy ? 0, what is the ratio of to x/5 to x/6?

(A) 1
(B) 36/25
(C) 6/5
(D) 5/6
(E) 25/36
Explanation:

First, find the ratio of x to y; it will be x/y = 6/5, we get that from 5x=6y.

The easiest here would be to pick numbers. This will keep the brain in one piece. Let's say x=12 and y=10; this fits our condition: 5x12=6x10.

Now, let's combine the ratio and the values we have for x and y:

(12/5) / (10/6) = 12/5 * 6/10 = 36/25

This is the final answer.


Didn't the question ask for x/5 to x/6... Haha wouldnt that just be 6/5 ??]

I dont mean to nitpick.... :roll:
