(1) says :
5x = 2y
=> x/y = 2/5

Sufficient

(2) says

2y = 7x – 8

But from this we can't evaluate x/y for a definite value.
So Insufficient.

subhashghosh - the question doesn't say that x and y are not non zero.
They could be zero!!!

What happens then?

0/0 is not defined, so you can ignore what if x and y = 0 in (1). Then in (2), the equation will fail if x = y = 0, because then the equation becomes 0 = -8, which is absurd.

Ask MGMAT about the same and let us know. Either the OA should be "C" or the condition $$y \ne 0$$ should be provided.

I agree with fluke . Because... if either x or y is negative... then the ratio is a negative result

The question here asks to find the value of x/y?,

So should'nt we concentrate on the option which provides us with the value of the above question and the 1st option does.

So the correct option must b A.
