I'm wondering how does the rpm on different gear affects mileage. I'm not even sure it affects at all.

Let's say on a 6 gear, 15000 rpm motorcycle engine system. My questions are

  1. Will 6k rpm on first gear and 6k rpm in 6 gear consume same amount of fuel?
  2. Same rpm, same gear one on a straight road, one is climbing uphill, will these consume same amount of feel?

The speeds will vary considerably in such configurations, feels like the consumption will be same, but when I think about it there are differences, hence I'm confused.

It depends on how far you need the throttle open in each of your described situations to maintain the 6000 RPM. If the throttle is in the same position in both situations, then the same amount of fuel will be used per revolution. If one situation requires a more open throttle, then more fuel will be used per revolution.
