NOR = (A + B) compliment.
-ve AND means bubble at the input,= NAND.
A comp + B comp = A.B comp.
-ve AND means bubble at the input,= NAND.
A comp + B comp = A.B comp.

NOR gate is equivalent to AND gate with its inputs bubbled. Means NOR gate = Inputs bubbled AND gate.
Similarly NAND gate means inputs bubbled or gate.
Similarly NAND gate means inputs bubbled or gate.

In this problem we can solve like also,
At first we have taken 2 input as 1 & 0. In the nor gate the output is 0.
It is equivalent to negative and gate because in and gate we will got 0 as output. So in negative and gate it must be 1.
Hence 2 input-nor gate is equivalent to negative and gate.
