I am generally perplexed by the following question types & don't have a concrete strategy to solve them.
I) Must be True
II) Maybe True
III) Could be True
IV) Always True
V) Cannot be True
The question types usually have three expressions or the expressions themselves are the answer choices. Need to understand the difference between them & the number of test cases i should test to satisfy them.
The most difficulty i face is when the questions involve inequations & requires testing numbers. I do follow the (>1, 1 to 0, 0, 0 to -1, -1, <-1) number testing approach, however it is too time consuming sometimes.
Has anyone devised a solid strategy to hit these questions outta the park?
I am sure there are others who find these questions challenging.
Requesting the Quant experts (

Good question.
Here is how I approach it:
I) Must be True - Same as IV below
II) Maybe True - Same as III below
III) Could be True - Same as II above
IV) Always True - Same as I above
V) Cannot be True - Not same as anything above
For
Must be true or
Always true, you need to find an answer that cannot be made false, or said differently has to satisfy the equation/quantity in question. On the flip side, a
could be true or
may be true basically says that the answer may or may not be true.
Note that
Cannot be true is the same as
Must be true, except it is negated.
As far as strategy, I've found that plugging in smart numbers always helps. What do I mean by smart? If the answer choices are all multiples of 3, do not pick 100.
Does this help?
