Plain-text version
If R is a matrix of 8 × 9, Q is matrix of order 4 × 8 and P is matrix of order 3 × 4, then the order of the new matrix PQR is (A) 9 × 3 (B) 3 × 9 (C) 9 × 3 (D) 3 × 3
Also written as: If R is a matrix of 8 * 9, Q is matrix of order 4 * 8 and P is matrix of order 3 * 4, then the order of the new matrix PQR is
