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.
