    this is damn cheap !!!!

    assume limo to be x
    assume sedan to be y
    limo costs triple sedan ----- that gives x = 3y
    and limo for 2 days and sedan for 3 days costs 675
    --- that gives 2x +3y = 675
    solve these 2 equations
    6y + 3y = 675
    y = 75
    there fore x = 225 -- the cost of limo
