If y is an integer and y = x + x, is y = 0? (1) x < 0 (2) y < 1 I rephrased the original question as Is x<0? Statement 1 : SF Statement II : if y<1; x+x<1..on solving we get 2 ranges for x  X<0 or,  0<X<0.5 Basis this II is insufficient.. Where am I going wrong ?

If y is an integer and y = x + x, is y = 0?
(1) x < 0
y = x + x y=x+x y=0 SUFFICIENT
(2) y < 1 TRICKYYYYYY I originally said it was insufficient because it tells us nothing about the sign. However, if y is less than one and is an integer and it is equal to x+x then it must be zero!! SUFFICIENT

I rephrased the original question as Is x<0? Statement 1 : SF Statement II : if y<1; x+x<1..on solving we get 2 ranges for x  X<0 or,  0<X<0.5 Basis this II is insufficient.. Where am I going wrong ? point to remember is y is an integer if y<1 , then y could be 0, 1, 2 and so on .. here according to the second condition if x= 0 then y= 0 , if x = ve then Y = 0 , if x = +ive like 1 then second choice only will fail, if x = 0.5 then y cant be less than one, if x=.2 or .3 then y cant be integer.

stat 1: X<0 => y = x+x =0 suff stat 2:y is in integer & y<1 => y<=0 ...y can be less than zero only when x is less than zero => y = x+x = 0 and for y=0...ntn to calculate suff => Ans D
