Is |15 - m| + |m - 15| > 15?
First of all since \(|15 - m| = |m - 15|\), then the question asks whether \(|15 - m| + |15 - m| > 15\) --> is \(2*|15 - m| > 15\)? --> \(|15 - m| > 7.5\)? --> is \(15 - m > 7.5\) or \(-(15 - m) > 7.5\)? --> is \(m<7.5\) or is \(m>22.5\)?
(1) m > 6. Not sufficient.
(2) m < 7. Sufficient.
Answer: B.

(1) m > 6. Not sufficient.
(2) m < 7. Sufficient.
Answer: B.

Hi Bunuel,
Since in the question stem, it is not mentioned that m is an integer, why can't we use m=6.5?
Thus,
15-6.5 !>7.5
Thus, even the option (2) is not sufficient, Answer should be E.
Please correct me if I am wrong. This is the main confusion I have in DS questions, when to use fractions and when to not!
