Short answer: the total XP of all the bandits is the XP awarded to the whole group, which is then divided among them, so they should get 110 each, yes.
Longer answer: it's easy to get distracted by the fairly complex guidelines for estimating encounter difficulty that start on pg. 81 of the DMG, but your question is more oriented toward the much shorter section on pg. 260: Experience Points. There, the rules are basically:
- Add up all the XP values of the monsters defeated (not necessarily killed, but captured, run off, etc.)
- Divide that total evenly among party members (which includes any NPCs the group got "substantial assistance" from during the encounter).
That's it; the math for estimating difficulty is a lot more complex, with multiplying the "total" depending on how outnumbered the party is, and reducing that if they're five or more, but for awards, you just use the raw amount of the monsters, added together and divided between party members.
Things that aren't RAW that you'll sometimes find DMs doing might be:
- Awarding the adjusted experience total for the encounter instead of just summing up from the individual monsters, so that the reward is scaled closer to the difficulty of the encounter as a whole
- Giving lower-level characters a higher share of the XP when divvying it up, because they're theoretically at a greater risk during the encounter.
...but those aren't RAW, in case you hear differently.
