The store sells large and small chocolate bars. A large chocolate bar is twice as expensive as a small one. A lady who entered the store bought 5 large chocolate bars and 3 small ones. If she had instead bought 3 large chocolate bars and 5 small ones, she would have spent 20 rub. less.
How much does a large chocolate bar cost and how much for a small one?

We have a prince who wants to marry. And we have three girls; two of them dream of getting married, while one doesn't want to at all.
The prince decided not to overcomplicate things and set a condition: he would marry the one whose kettle boils faster, given that the kettles and the water level in them are identical for all three. Pouring water out or adding more is also not allowed.
The trick is that he married the one who didn't want to get married, because her kettle boiled faster. Attention, question: how could this have happened?
