If x and yare positive, is x/y greater than 1 ?
Is\(\frac{x}{y}>1\) ? --> as given that\(y\) is positive we can safely multiply both parts of the inequality by it --> so the question becomes "is\(x>y\) ?" OR: is\(x-y>0\) ?
(1) xy > 1 --> product of two numbers is more than one we can't say which one is greater. Not sufficient.
(2) x - y > 0. Directly answers the questions. Sufficient.
Answer: B.
