Solution:

The correct answer is: 0

*Answer can only contain numeric values

QUESTION: 4

What will be the output of the logic gate formed by the circuit drawn below for inputs

Solution:

The above figure behaves as a NAND gate, hence for and output = 0

The correct answer is: 0

*Answer can only contain numeric values

QUESTION: 5

What is the output of the Boolean expression for the output of the logic circuit drawn below for A = B = C = 1

Solution:

The correct answer is: 1

*Answer can only contain numeric values

QUESTION: 6

What is the output for X = 1, Y = 0 for the logic circuit drawn below :

Solution:

The truth table for the above circuit is.

Hence, for X = 1, Y = 0, output = 1

The correct answer is: 1

*Answer can only contain numeric values
