Hi can anyone help me with this problem??

Any information possible that may help me answer this question

What is the difference in cents between a 'c' 12 perfect fifths above C2 and a 'c' 7 octaves above C2 and what is the actual frequence?

Thanks

One of the anomalies which lies at the heart of tunings systems used in western music can be demonstrated like this:


start at a certain pitch;
go up by four perfect fifths;
go down by two octaves.

Where you end up is a major third higher than where you started. You can see this on a piano keyboard:
