I think Rahul's first post says it all. In the first go even i could also come up with X=1 only considering both statements together. Thus OA has to be C with X = 1 and Y = -1.

Thanks Rahul, this means that i can apply this method of even power and odd power applicable to only 9 because it has also got a cyclicity of 2?
How about other numbers such as 2, 3, 5?
Can you provide some more similar questions or probably a link on this topic for practice?

Finding the Unit digit
Pls help with the following problem. Unit digit of (264)^103 + (264)^102 = ? My answer: 5 First Term 4 has a cyclicity of 2. Thus 103/2 would leave a remainder of 1 =>4^1 = 4. Second Term 4 has a cyclicity of 2. Thus 102/2 would leave a remainder of 0 =>4^0 = 1 Therefore, 4 + 1 = 5 is the unit digit...

Hi,
I might be going a bit off topic, but what if Y = 0 in this case? How do you justify the answers?
I will be glad if you can clear this doubt.
Thanks
