NIMCET 2018 Question Paper with solutions

In NOR gate, if one input is 0 and other is 1. Then, the output will be 0. If both inputs are low. Then, the output is
1. So. NOR gate is not a answer.
In NAND gate, if one input is 0 and other is either 0 or 1, the output is high. So, NAND gate is a answer
