Q1:

The BCD addition of 910 and 710 will give initial code groups of 1001 + 0111. Addition of these groups generates a carry to the next higher position. The correct solution to this problem would be to:

A ignore the lowest order code group because 0000 is a valid code group and prefix the carry with three zeros

B add 0110 to both code groups to validate the carry from the lowest order code group

C disregard the carry and add 0110 to the lowest order code group

D add 0110 to the lowest order code group because a carry was generated and then prefix the carry with three zeros

ANS:D - add 0110 to the lowest order code group because a carry was generated and then prefix the carry with three zeros
