Question 172
Sashka had $3$ baskets with apples. The baskets contained $12$, $14$ and $22$ apples. Sashka is allowed to choose two of her three baskets and move apples from one basket to the other. In doing so, she must move from one of the chosen baskets to the other exactly as many apples as there are in the basket to which she adds (moves) the apples. Sashka made three moves of the described kind and then all baskets contained the same number of apples. How did Sashka do it?
