Hi richachampion,
This question is really just about 'math vocabulary' and paying careful attention to the numbers that we're given to work with.
We're told that X is one of the four listed values. We're asked for the value of X.
1) The HUNDREDTHS digit of X is greater than 6.
This Fact narrows down the options to 2 possibilities: B and C - but we don't know which one is X.
Fact 1 is INSUFFICIENT
2) The THOUSANDTHS digit of X is less than 4.
This Fact narrows down the options to 2 possibilities: A and B - but we don't know which one is X.
Fact 2 is INSUFFICIENT
Combined, we now have to look for the 'overlap' - the option(s) that 'fit' BOTH Facts. Based on our prior work, there's ONLY one possibility: value B.
Final Answer: C
GMAT assassins aren't born, they're made,
