Test Code 31

[Cedars]

If r>0 and s>0, is r/s<s/r?

1) r/3s = 1/4
2) s = r+4

SPOILER:
oa: D

[pleasant_raj]

Statement 1:
r/3s=1/4
r/s=3/4 and s/r=4/3
Therefore, r/s<s/r -----Sufficient

Statement 2:
s=r+4
This implies that s>r (Since both r and s are positive i.e. >0)
Therefore r/s<s/r -----Sufficient

Answer D.

I agree with raj, the answer is D.

Here's a trick that could save you time if the problem were more complex:
Since both numbers are positive, you can actually think of the question as asking is (R^2) > (S^2), or even is R > S. This thinking works because you are dealing with inequalities and they are both positive.
