It is 10:41pm in 2 hours and 40 minutes what time will it be?

10:41pm

10 hours, 41 minutes (pm)

Add 2 hours and you get 12 hours, 41 minutes. (am)

Then add the 40 minutes and you get 13 hours, 21 minutes. (am - NOT pm)

Because it's a 12 hour clock (you can assume from the am and pm), it can only be in the 12 hour format, so you can't have 13:21, because that's in the 24 hour format and it also means that it's 1:21pm. So your final answer would be 1:21am.
