If \(\frac{p}{q} < 1\), and p and q are positive integers, which of the following must be greater than 1 ?


(A) \(\sqrt{\frac{p}{q}}\)

(B) \(\frac{p}{q^2}\)

(C) \(\frac{p}{2q}\)

(D) \(\frac{q}{p^2}\)

(E) \(\frac{q}{p}\)


IMPORTANT: For questions like this, where you need to test each answer choice, the test-makers will often make D or E the correct answer (because they want to eat up your valuable time :-)). So, in these situations, always begin with E and work your way up.

E. Is q/p > 1?
Well, we're told that p/q < 1.
Since q is a positive integer, we can multiply both sides by q to get: p < q
Since p is a positive integer, we can now divide both sides by p to get: 1 < q/p
So, answer choice E must be true.

Answer: E

I considered smart numbers
p = 2 and q = 3 since we want p/q < 1 so 2/3 is less than 1
now put values in options, only option E hold true
