| 29. |
If the functions w, x, y, z are as follows.
w = R + PQ + RS ,
x = PQR S + PQR S + PQ R S
Then |
| [A]. |
w = z x = z | | [B]. |
w = z, x = y | | [C]. |
w = y | | [D]. |
w = y = z |
Answer: Option A
Explanation:
Use k-map, then it will be easy.

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

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. |

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'. |
