Kudos for
R.A.EGIVEN: x + y = 4 and xy = 0
If xy = 0, then EITHER x = 0 OR y = 0
Let's examine each possible case:
Case i) if x = 0, then y = 4 (since we're also told that x + y = 4)
Case ii) if y = 0, then x = 4 (since we're also told that x + y = 4)
In case i, Quantity A is greater than Quantity B
In case ii, Quantity B is greater than Quantity A
Answer: D
Cheers,
Brent
