At a certain hospital,89 children were born in the month of June.If more childrenwere born on the fifteenth of June than on any other day in June,what is the least number of children that could have been born on the fifteenth of June.

医院有89个孩子生在6月,如果在6月15号出生的孩子最多,那么15号出生的孩子至少有多少个?
算法:89除以30(6月30天),得3还少1个,此时就是6月每天出生3人(其中有某一天是2人),若要让15号最多,只需加1,就可以了,所以是4人.
