If P and Q are non zero integers, is P+Q even?

(1) \(P^Q\) < 0

(2) 3*P is an even integer.

[1] : p has to be negative and q has to be odd

p = -3 & q = 1 or - 1 ; \((-3)^1\) = (\(-3)^-1\)

p can be odd or even hence p + q = odd + odd = even or even + odd = odd - hence 1 is not sufficient

[2] p = even but we do not know about q

1 & 2 : p + q = odd = C

from 1, we can say that P will be a negative odd or an even integer, this will give us 2 values for the question

from 2, we can just say that P will be an even integer

Now when we combine, we can say that p is an -ive even integer and for 1 to hold good, Q has to be an odd integer

This will make the question as a No

C
