Chain Situation - old cogs?
What should I do in this chain situation.
On my mt bike. I noticed that my chain was down to 75%. The number where I usually switch chains out.
Switched to a new chain. PC 1120 Same as older one. As I always change chains around 50% to 75% usually.
I put new chain on.
Now It is skipping in most of the gears.
I feel my cassette is perhaps too worn. So the case of too new chain on old cassettes?
What should I do?
i) try to trim my chain down a bit more maybe it won't skip
ii) get a whole new chainrings and cassette, cogs. with new chain
iii) do nothing
iv) try another chain?
v) what for your suggestions?
What do you all suggest is best option? thanks

Skipping gears after new chain is usually a sign of worn out cogs. I'd start with replacing the cassette. I've read a rule of thumb, of 1 cassette for every 3 chains. Chainrings are less likely to be worn out, but could stand to be inspected.

Make sure the wheel is installed straight, the new chain is of the correct length and has no stiff links, and the rear derailleur cable is tensioned correctly. If that all checks out, replace the cassette.

It's time for a new cassette. Another option is to put the old chain back on and ride it awhile longer. In theory this may be harder on the chainrings, YMMV.

I'd follow Rolla's advice to check everything else first, but I suspect your solution is going to be to replace the cassette.
Chainrings eventually wear down too but worn chainrings can usually be identified with a visual inspection. If your chainrings look pointy on the tops, it's time for new ones.
