Is mod x = y - z
1) x + y = z
2) x < 0
OA.. C
Corrrect me if i am wrong in below thought..
A and B individually are not sufficient.
Given from A x=z-y
Given from B x <0; so x is -ve
From A and B,Equation x=z-y is -ve.
So |x| is +ve by definition, |x| has to be equal to y-z cause z-y is -ve.
So C is OA

Same question, only now stat. (2) says x>0. What's the answer then?

Yes i agree with shovan85 since from A and B..z-y is +ve, implies y-z is -ve
As a result |x| cannot be y-z.
