Logic Gates question from JEE Main 2025 (2 Apr, Shift 2)

Answer: (c)

1. Inputs $1, 1$: NAND output $= \overline{1\cdot 1} = 0$.
2. Both NOT gates give $0$, so the OR gate output $= 0 + 0 = 0$.
3. $P$ = AND(NAND output, OR output) $= 0\cdot 0 = 0$.
4. $Q$ = NOR($\overline{0}$, OR output) $= \overline{1 + 0} = 0$.
5. So the answer is (c) $P = 0, Q = 0$.
