Question 78

If a,b and c areintegers,is(a-b+c)>(a+b-c)?
I. b is negative.
II. c is positive.

Solution

For (a-b+c) > (a+b-c)
Considering first statement alone
if b<0, we can't say anything affirmative about inequality as information about c is unavailable.
Considering second statement alone, 
if c>0, we can't say anything about b.
Now if we consider both statement together 
i.e. b<0 and c>0, then term (-b+c) will be positive and additive to a whether term (b-c) will be negative and subtracting from a.
Hence (a-b+c) > (a+b-c).
And answer will be D.
