Hi All,
This is an example of a 'Symbolism' question - the prompt 'makes up' a math symbol, tells you what it means, then asks you to perform a calculation using it. When dealing with these types of symbols, it often helps to jot down a few examples, so that you understand the work that will be required of you when you deal with the actual question that is asked.
Here, we're told that [X] is the LEAST INTEGER greater than or equal to X. Thus...
[2] = 2
[.5] = 1
[-1.5] = -1
Etc.
When we're told that [X/2] = 0, this implies that whatever is inside the symbol is a limited range that is LESS THAN OR EQUAL TO 0....
For example:
[0] = 0
[-.5] = 0
[-.9999] = 0
Etc.
With this information, finding the value of X shouldn't be too hard...which answer will fit this pattern when you plug it into [X/2]?
Final Answer:
GMAT assassins aren't born, they're made,
Rich
