Can someone explain how "either of the 2" means both in Statement 2 ?
Hi rhushishah,
If you find that you're not clear on the meaning of a particular phrase in a Quant question, then it can sometimes help to come up with a simple example - to see if your example matches the 'description' in the text. With Fact 2, we're dealing with the phrase:
"The TENS digit of r is less than either of the other two digits of r."
In the prompt, we're told that R is a 3-digit number (any number from 100 to 999, inclusive). With the extra information in Fact 2, we have a 'restriction' that we have to deal with.
Does the number 123 fit that description? NO, because the TENS digit ("2") is NOT less than either the of the other two digits (the "1" and the "3") - it's only less than one of them.
Does the number 523 fit that description? YES, because the TENS digit ("2") IS less than either the of the other two digits (the "5" and the "3").
Thus, with Fact 2, we can only use certain types of 3-digit numbers (ones that have a 'middle digit' that is smaller than the other two digits).
GMAT assassins aren't born, they're made,
