Question:

To get an output Y=1 in the given circuit, which of the following inputs will be correct?

A=1;B=1;C=0

A=1;B=0;C=1

A=1;B=0;C=0

A=0;B=1;C=0

Solution:

Here the logic gates used are OR gate, AND gate. So, if we input values 0 and 1 to the OR gate, the output will be 1. This output along with another input 1 will be used as input for the AND gate. Thus, the final output is 1.
