Answer:

Answer

Let A the row matrix representing the quantities BOUGHT, then A=[

] is a 1×3 matrix.

Let B be the column matrix representing the cost of mangoes,APPLES and bananas per dozen the B=

⎣

⎢

⎡

⎦

⎥

⎤

is a 3 x 1 matrix

The total cost is given by the product AB

and AB=[

]

⎣

⎢

⎡

⎦

⎥

⎤

=[144+90+24]=[258]

Hence, the total cost is Rs 258
