* Three farmers were selling chickens at the local market. | |
* One farmer had 10 chickens to sell, another had 16 chickens to sell, | |
* and the last had 26 chickens to sell. In order not to compete with | |
* each other, they agreed to all sell their chickens at the same price. | |
* But by lunchtime, they decided that sales were not going so well, | |
* and they all decided to lower their prices to the same lower price point. | |
* By the end of the day, they had sold all their chickens. | |
* It turned out that they all collected the same amount of money, | |
* $35, from the day's chicken sales. | |
* | |
* What was the price of the chickens before lunchtime and after lunchtime? | |
