In the following circuit what are P and Q

Options

  1. AP=1, Q=0
  2. BP=0, Q=1
  3. CP=0, Q=0
  4. DP=1, Q=1

Correct answer

B. P=0, Q=1

Step-by-step solution

The given circuit is as shown The truth table for P can be shown as The truth table for Q can be shown as Thus, Q is l for any value of P . So, the values satisfying given condition are, P=0, Q=1
