NIMCET 2023 — Reasoning PYQ
NIMCET | Reasoning | 2023
A bulb in the staircase has two switches, one switch is at the ground floor and the other one is at the first floor. The bulb can be turned ON and also can be turned OFF by any of the switches irrespective of the state of the other switch. The logic of the switching of the bulb resembles
Choose the correct answer:
A.
XOR gate
(Correct Answer)
B.
AND gate
C.
OR gate
D.
XNOR gate
Correct Answer:
XOR gate
Explanation
Option (a) In this scenario, the behaviour of the switches can be represented by an XOR gate. An XOR gate, also known as an Exclusive OR gate, produces an output of "true" (or ON) only when the number of input signals that are true is odd. In this case, the bulb will be ON when either switch is flipped, regardless of the state of the other switch.
