一个村庄要在8天之内建一座320米长的大坝.已知16个工人3天可以建好96米.那么根据此,还要加多少工人?
96/3/16 =2 (米)一个工人每天能修2米. 320/8/2=20 (个) 工人, 所以还需要加4个工人.

祝你学习进步.

这题不严谨。已经用了3天,建造了96米,也就是剩下的224米要在5天内完成,即每天要建造44.8米。每个工人每天建造两米,所以这5天内每天需要22.4个工人,取整,则需要增加7个工人。

解题思路:先求出作文类、奥数类、英语类、文艺类、科普类任意借两种一共有多少种借法,再加上1,这名学生无论怎么借,他都要与前边的借法重复.

5×4÷2,
=20÷2,
=10(种);
10+1=11(名)
答:至少11名学生中一定有两人所借图书的种类完全相同.
故答案为:11.

点评:
本题考点: 抽屉原理.

考点点评: 本题利用到了抽屉原理:把借的方法的总种数看成抽屉,要有2人借的种类完全相同,那么人数就要比借的方法多1.
