When Y is divided by 2, is the remainder 1?
(1) (-1)^(Y+2) = -1
(2) Y is prime.
OA is (A)
Explanation is that using statement 1, Y cannot be even and hence can take odd numbers 1,3,5,,,.
My doubt is that in the question nothing is mentioned whether y is positive integer or negative integer. Hence it can also be -1,-3,-5 .Even then its satisfies the equation and remainder is not 1.
after combining the 2 statements still we cannot solve it hence the answer should be E.
