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.
