Assume P, Q, R and S are matrices of order 2 x m, k x n, m x 2 and 2 x 3 respectively. The restrictions on k, m and n, so that PQ + RS is defined are Option 1: m = 3, n = 2 Option 2: m = n, k is arbitrary Option 3: m = k, n is arbitrary Option 4: m = k = 2, n = 3

The answer is 'm = k = 2, n = 3'. View full solution:

$m = 3, n = 2$

$m = n$ , $k$ is arbitrary

$m = k$ , $n$ is arbitrary

$m = k = 2, n = 3$

✅ Correct Option: 4
