43:  

What is the result of the following expression
(1 & 2) + (3 & 4)

A.	1
B.	3
C.	2
D.	0
	Answer Report Discuss
	Option: D Explanation : Code for  1 is 0001 and for 2 is 0010. On performing AND operation of these we find 0000. Similarly, code for 3 is 0011 and for 4  is 0100. On performing AND we get 0000  so according to expression (1&2)+(3&4) we will perform OR operation of (1&2) and (3&4)  i.e. 0000+ 0000=0000. So answer will be 0. Option 'D'.
