The answer a is incorrect. Now, for all values of pqrs (0000 to 1111) must satisfy the conditions.

For the example 1010, x evaluated to 0. While z is evaluated to 1. So the answer is wrong.

Can anyone please help me solving it using k map, since the expression of 'y' and 'z' involves both min-terms and max-terms?

X=PQR'S' +P'Q'R'S' +PQ'R'S'.

If x is equal to this term, the answer will be w=z x=z'.
