If x and y are prime numbers, is y(x-3) odd?

A. Statement 1 alone is sufficient but statement 2 alone is not sufficient to answer the question asked.

B. Statement 2 alone is sufficient but statement 1 alone is not sufficient to answer the question asked.

C.Both statements 1 and 2 together are sufficient to answer the question but neither statement is sufficient alone.

D. Each statement alone is sufficient to answer the question.

E. Statements 1 and 2 are not sufficient to answer the question asked and additional data is needed to answer the statements.

Q: Is y(x-3) odd OR Is y(x-3) even?

Even*Any Integer=Even

(1)x>10

x=Odd.

x-3=odd-odd=even

If (x-3) is even; (x-3)*Any integer=Even.

Thus;

y(x-3) = Definitely even.

Sufficient.

(2)y< 3

The only prime number less than 3 is 2, which is even.

Again; Even*Any integer=Even.

Thus,

y(x-3) = Definitely even.

Sufficient.

Ans: "D"
