Consider 1)+2) we have (50;60) interval.

_______49__50_______60____64

But what to do with highlighted parts?
Virtually we are asked if 49<N<64?
we miss 2 intervals: (49;50) and (60;64)
Having (50;60) we can't say that (49;64) is true.
Looks like (E).

OA for this question is C.

Question: is \(49<n<64\)? or is \(n\) in the range (49,64), not inclusive.

(1)+(2) \(50<n<60\) --> ANY \(n\) (any number) from this range IS in the range (49,64), so the answer to the question "is \(49<n<64\)" is YES.

Hope it's clear.
