1 Answer

Answer :

Ans: B
 The correction to be applied in decimal adder to the generated sum is 00110.
 When the four bit sum is more than 9 then the sum is invalid. In such cases, add +6(i.e.
0110) to the four bit sum to skip the six invalid states. If a carry is generated when adding 6,
add the carry to the next four bit group .
