At the cost of a half-liter bottle of 2 rubles 87 kopecks, a quarter cost 1 ruble 49 kopecks. Someone noticed that the value of a quarter (1,49) in the degree of the value of a half-liter (2,87) is equal to the number "pi" (3,14159) with an accuracy up to the fourth sign after the fifth (the difference is 0,00076). The Ostryaks concluded from this that, under the Communists, prices are not taken from the ceiling, but are established on a scientific basis.
