|It should be 1 actually.|

|No It would be 3, Because the output 1 NAND gate is X'+Y'. So it requires more than 1 NAND gate.
In this we gave 2 inputs suppose X, Y to the first NAND and we get X'+Y'.
Again in second NAND we get X'+Y'.
These two outputs fed to the input of third NAND and the output is ((X'+y').(x'+y'))'.
After minimize it we got OR output as X+Y.
