Solution

The number of articles sold by each school can be written in the matrix form as follows:

`X=[[40,25,35],[50,40,50],[20,30,40]]`

The cost of each article can be written in the matrix form as follows:

`Y=[[25,100,50]]`

The fund collected by each school is given by

`YX=[[25,100,50]][[40,25,35],[50,40,50],[20,30,40]]`

`YX=[[7000,6125,7875]]`

Thus, the funds collected by schools A, B and C are Rs 7,000,  Rs 6,125 and Rs 7,875, respectively.

The total fund collected = Rs (7000 + 6125 + 7875)
                                   = Rs 21,000

The situation highlights the helpful nature of the students.
