Solution


Q.

If A is a 3 × 2 matrix, B is a 3 × 3 matrix and C is a 2 × 3 matrix, then the elements in A, B and C are respectively:
1 6, 9, 8  
2 6, 9, 6  
3 9, 6, 6  
4 6, 6, 9  

Ans.

(2)

Ans.     6, 9, 6

Explanation:

The number of elements in m×n matrix is equal to mn.

∴   Elements in A = 3 × 2 = 6

∴   Elements in B = 3 × 3 = 9

∴   Elements in C = 2 × 3 = 6
