    X 400 300 100
    Y 300 250 75
    Z 500 400 150
    Find the total cost incurred by the organisation for X and Z villages separately using matrices. Write one value generated by the organisation in the society.

    Answer:

    The number of attempts made in three villages X, Y and Z can be represented by the \[3\times 3\]matrix. \[f:N\to R\] and the cost for each made per attempt can be represented by the \[3\times 1\]matrix By matrix multiplication, the cost incurred by the organisation for the three villages Hence, the total cost incurred by the organisation for the three villages separately are Rs. 30000, Rs. 23000 and 39000. Value The organisation in the society generated the value of cleanliness for the women welfare.
