If x, y, and z are consecutive integers, and x < y < z , is x even?
(1) x + y is odd.
(2) x + z is even.
is x even, with x,y,z being consecutive and x<y<z
St 1: x+ y = odd. And x< y
Case 1: 1+2 = 3 (ODD); 4+5 = ODD; 5+6 (ODD)
Not suff x can be odd or even answer is ODD
St 2: x + z = even. x = 4, y = 5, z = 6 answer is even. x =3, y = 4, z= 6 answer is even.
odd + odd = even and even+ even = even
Not suff
1) + 2) No conclusion. Ans is E
What is the OA?
