C.

1) x is a fraction. y can be anything. Hence not suff
2) y is a fraction. x can be anything. Hence not suff

Both

X and Y can be both fractions hence suff to say that x+y not equal xy
Remember 0 is a positive integer

good one..

i missed the fraction part initially.

x = 0, y= 0 then x + y = xy

x = 1/2, y = 1/2 then x +y != xy

hence E.

(E)

x and y can be either 0 or fractions.. which makes both conditions insufficient.

Thats the human mind. If you say neither a +ve integer nor a -ve integer then most of people will choose x and y as integers.
