Q1:

Solve this BCD problem: 0101 + 0110 = ________.

A 00010111BCD

B 00001001BCD

C 00010001BCD

D 00010011BCD

ANS:C - 00010001BCD

0101 = 5.
0110 = 6.
5+6 = 11.

Here, final answer is 11. So we can split 11 as 1 and 1.

The equivalent value of 1 = 0001 (1st split up).

The equivalent value of 1 = 0001 (2nd split up).

11 = 00010001 is the answer.
