chetan2u · Answer

Is x < 0 ? (1) y + x < 0 If y>0, then x is surely negative. If y<0, say y=-10, then x could be 2, or 9 or -18. Insufficient (2) y > 12 Nothing about x. Combined y>0, so x<0. Sufficient C

Question is asking  Is x negative

Let’s dig down 1st statement  y + x < 0 
We don’t know the value of  y,  if y is negative integer and it’s magnitude is greater than x then even if x is positive or negative condition will still be true. So  Eliminate A and D

And with 2nd statement  y > 12 
We don’t know about x.  Eliminate B

Taking both statements together;
We know that y is positive, so x should be negative to satisfy the first statement.  Sufficient

Answer is  C
