MCQ

The restriction on n, k and p so that PY + WY will be define are:

✓
k = 3, p = n
B
k is arbitrary, p = 2
C
p is arbitrary, k = 3
D
k = 2, p = 3

✓

Answer

Correct option: A.

k = 3, p = n

Given: $ \text{x}_{2\times n}, \text{y}_{3\times k},\text{ z}_{2 \times p}, \text{w}_{n \times 3}, \text{p}_{p\times k}$
Now, $\text{py + wy} = \text{p}_{p \times k}\times \text{y}_{3\times k}+\text{w}_{n\times3}\times\text{y}_{3 \times k}$
On comparing, k = 3 and p = n
Therefore, option (A) is correct.
