The task is especially relevant in the context of the financial crisis and for tax officials, although it was created in the 18th century.
Two, Andrei and Fedor, exchange money (in order to avoid taxes). First, Andrei gave part of his money to Fedor, then Fedor to Andrei, then again to Andrei Fedor, and finally, Fedor gave Andrei the last time, and after this transfer everyone got 160 rubles. The amount of money transferred each time was equal to the amount of money from the recipient.
How much money did Andrei and Fedor initially have?
PS, since the task itself is not complicated, it is supposed to solve it in the mind as soon as possible, since it is precisely such decisions that often have to be made in a financial crisis.
