Concept: The question tests on the application of Algebra in a DS format


Simplifying the following expression, we have


=xy(x−y) / (y−x/xy)



So all we need is the value of x and y or the value of xy to answer the question

Statement 1: xy = 6. This is sufficient to answer the question as shown above. Answer Options could be A or D  (Sufficient)

Statement 2: x - y = 1. This statement is insufficient as we can only derive the fact that x = y + 1, and we can get multiple answers for the same. (Insufficient)

Option A
