[GMAT math practice question]
(function) If the symbol # represents one of addition, subtraction, multiplication, or division, what is the value of (2 # 1)?
1) 2 # 2 = 1
2) (–1/2) # (-1) = 1/2
=>
Forget conventional ways of solving math questions. For DS problems, the VA (Variable Approach) method is the quickest and easiest way to find the answer without actually solving the problem. Remember that equal numbers of variables and independent equations ensure a solution.
