我国古代有位丞相．他听说有位叫张邱建的算学大师很是了不起，于是想亲自试一试，看看他到底是不是像传说的那样神算．一天．丞相邀请张邱建到其府上，问他：“现有钱一百文，要买一百只鸡．如果公鸡每只五文钱。母鸡每只三文钱，小鸡三只一文钱．这一百只鸡该如何买法？”张邱建略加思索后答道：“那就买4只公鸡，18只母鸡，78只小鸡便成．”丞相一算。果然花了一百文钱，买的鸡又恰好一百只．
Formerly there was a prime minister in the ancient times of our country ,he heard a mathematics master named Zhang Qiujian. Then the prime minister wanted to try Zhang Qiujian himself to see if he was such remarkable as the person who was famed .One day the prime minister invited Zhang Qiujian to his mansion and asked： ＂Now I want to cost ￥ 100 to buy 100 chooks . If each cock ,each hen and three ehieidings are worth ￥ 5, ￥3, ￥ 1 respectively ,how will I buy ？ ＂ Zhang Qiujian thought it for a while and answered ： ＂You can buy 4 cocks , 18 hens and 78 chicidings . ＂The prime minister calculated and found as expected he would even cost ￥ 100 to buy 100 chooks .
