What is the value of f(a,b) + g(a,b) ?(1) f(a,b) = 0This could be \(a,b=0\) and \(f(a,b) + g(a,b)=0\); or could be \(a=0\) and \(b=1\) and \(f(a,b) + g(a,b)=1\). Not sufficient (2) g(a,b)= 0 This works only for \(a,b=0\) so \(f(a,b) + g(a,b)=0\). Sufficient

(1) f(a,b) = 0 (2) g(a,b)= 0 Can some one please explain the table to me . As of now I am not able to comprehend the two tables of f(a,b ) and g(a, b). in a 2*2 table , rows stand for something and column stand for something. In this sum what does row stand for and what does column stand for? Thank you members.

Yellow rows are the values of x, green columns are the values of y, and the red boxes are the outcomes of the functions f and g. The possible arguments of the functions f(x,y) and g(x,y) are x=0 or 1 and y = 0 or 1 and are defined by the following tables:
What is the value of f(a,b) + g(a,b) ?(1) f(a,b) = 0. According to the second table we can have the following cases: a=0, b=0 > f(a,b) + g(a,b) = 0 + 0 = 0; a=1, b=0 > f(a,b) + g(a,b) = 0 + 1 = 1; a=0, b=1 > f(a,b) + g(a,b) = 0 + 1 = 1. Not sufficient. (2) g(a,b) = 0. According to the first table we can have only the following case: a=0, b=0 > f(a,b) + g(a,b) = 0 + 0 = 0. Sufficient. Answer: B. Hope it's clear.

I guess a real GMAT question could have mentioned horizontal row is x and vertical column is y. Thank you.
