Solution

123+698 = 7121
This sum can be obtained by the following way
On taking digits in reverse order we get 321+896= 1217
On reversing the result we get 7121
Similarly for second sum 547+967 = 1514
On reversing the result we get 4151

Add each digit of both the numbers one by one
123
698
------
1+6==7; 2+9==11 ; 3+8; 11
put 7 as it is and carry forward 1 from 11 to the sum of the next two digits, and reverse the sum of the last two digits (3+8+1=12);is: 21
7121
Similarly : 346 + 594
3+5=8; 4+9=13; 6+4+1(from 13)=11
ans = 8311
