Happy Valentine's Day, Comrades!
Vladimir is getting some flowers for Nadezhda, his Valentine. Being of a precise analytical mind, he plans to spend exactly 24 rubles on exactly two dozen flowers. At the flower market they sell lilies (3 rubles each), roses (2 rubles each) and daisies (50 kopeks each). Vladimir knows that Nadezhda loves lilies. How many daisies will he get?
Note: Ruble and kopeks are basic monetary units in Russia. And one ruble is equivalent to 100 kopeks.
