hi
srikanth9502thanks for chipping in.
You mean to say that we are looking for unique property of n as even or odd.
Since n is odd satisfies
both hence n is odd
Since n is even
does not satisfy both hence n is even is not correct
Since I got two answers for n as odd / even for st 1 i rejected it.
Hey
adkikaniWhat is "both" that u are referring to?
Question - Is n odd?
If we answer a YES or NO for that then it is sufficient.
Statement 1)
For N to satisfy statement one.
N has to be odd.
So it answers our main question. Yes N is odd.
Statement 2)
For N to satisfy statement two.
N has to be odd here too.
So again it answers our main question. Yes N is odd.
Note - You dont even have to check for statement 2 because all the EVEN and ODD properties for addition are same as that for subtraction.
Example: 2 + 1 = 3 ---------- EVEN + ODD = ODD
2 - 1 = 1 ---------- EVEN - ODD = ODD
Hope it helps.
