If x and y are consecutive odd integers such that x < y, what is the value of y + x?
(1) The product of xy isnegative.
Just by picking numbers: -1*-3 =3 ; 1*3 = 3. Only number that does this is -1*1 (with zero in the middle) is negative. so SUFF.
(2) The sum x + y is the square of aninteger.-3+(-1) = -4. But -4 cannot be square of any integer. 3+1 = is sq of 2. 1 + (-1)
= 0; which is not square of anything. So different answers.
Answer is A
