    Let there be 2x science and 5x art books

    science books sold = 2x * 0.2 = 0.4x

    science books unsold = 2x - 0.4x = 1.6x

    art books sold = 5x * 0.2 = x

    art books unsold = 5x - x = 4x

    total books unsold = 1.6x + 4x = 5.6x

    5.6x = 2240

    x = 400

    2x science = 800

    and 5x art books = 2000
