915

Explanation:

Just add up the numbers in each of the columns (ones, tens and hundreds). Start with the ones column and carry any remainders over to the next colums

one's column : 4+1 = 5

ten's column : 9+2 = 11 (leave one as a place holder and move the remainder to next collum)

hundred's column : 8+1+0 = 9

Therefore the addition of 824 +91 = 915
