    Question Matrix Operations, determinnat and inverse

    Dear All,
    I need help on following question related to matrix..
    Suppose a man wishes to sell number of fans and bicycles. He gets profit of Rs, 50/- per fan and Rs. 500/- per bicycle.
    He purchased one fan at Rs. P and one bicycle at Rs Q. This man has total Rs. 55400/- to invest and has space of total 40 items.
    How many numbers of fans and bicycles he should purchase so that all the space could be occupied? Also find out the profit in Rs as well as in percentage that he gained? (350<P<380 and 2350<Q<2450)

    Note: First of all interpret the given information into matrix form. Then solve it by using matrix operations. By calculating determinant and inverse if needed.

    Suppose P is 350 and Q is 2350...
    Thanks,
