1: since x and y could be -ve and +ve, x and y could have any value.
also x+y can be 3.51 to 4.49. nsf.

2: same as above.
x - y can be 0.51 to 1.49.

togather also same.

if x+y = 3.51
x can be 2.02 to 2.51 and y can be 1 to 1.49 (but in the reverse order. i.e. higher the value of x lover the value of y and vice versa).

same for if x+y = 4.49

so nsf.

SAY x+y=m near to 4
x-y=n near to 1

x= m+n/2 ~ 4+1/2~2.5 ( it can be near to 2 or 3)

insuffcient.

Yes. I will also use the same approach Suresh used.. IMO E.

I guess if you start drawing number line for this question, it will kill time..

just consider , x+y= 4 and x-y=1 => x=2.5 now.. now depending on x+y>4 or <4 x can be closer to 3 or 2.
