'A'

1. x<0
any value for x <0 will lead to Y=0.

2. y<1
not sufficient because we do not know anything about X

1. x<0
any value for x <0 will lead to Y=0.

2. y<1

now it is given y=x+|x|.
hence,y should be 2x(if x is positive) or else 0.
in no case y is not going to be a negative integer...
it is given y<1 :idea:
hence the value of y should be a nonnegative integer.
0 is also a non-negative integer hence,we can say tht the value of y=0.

hence statement 2 is also suffucient.
therefore,the answer is D :-D

What about Y having a value of 2X when x is positive? That would give you a number of different values of y fo different values of x.

y is an integer so y=0,-1,-2 ..................

if X is positive then 2x is positive y <1 and integer per statement 2

so y has got to be 0

Great explanations....agree with D.

The minimum that y can be is 0. Since y is an integer and is <1, it must equal 0.

D too.

1 says x is -ve integer. y = 0 given that x is -ve.
2 says y cannot be -ve. if so, then y can only be 0.

great question and nice discussions. 8-) 8-) :P :P

0 is the only non-negative integer less than 1

(1) |x| = -x; y= -x+x = 0
(2) For y to be integer, |x| + x = an integer. if x<0 then y=0. If x>0 then y=2x (not possible as y<1). Hence y=0

D it is

0 is neither positive nor negative.
0 is even.
