一批学生划船，若乘大船，除一条船坐6人外，其余各船均坐17人；若乘小船，除一条船坐2人外，其余各船均坐10人．如果学生的人数超过100人，不到200人，那么学生为（）人。

A．110

B．126

C．132

D．142

E．152

答案

参考答案：D

解析：

设大船(x+1)只，小船(y+1)只，则17x+6=10y+2，即17x+4=10y，则y一定为8的倍数，又由于学生的人数超过100人，不到200人，则x=8，总人数为142人．

单项选择题

The metric assigned to each network depends on the type of protocol. Some simple protocol, like RIP, treats each network as equals. The ___44___ of passing through each network is the same; it is one ___45___ count. So if a packet passes through 10 network to reach the destination, the total cost is 10 hop counts. Other protocols, such as OSPF, allow the administrator to assign a cost for passing through a network based on the type of service required.A ___46___ through a network can have different costs (metrics). For example, if maximum ___47___ is the desired type of service, a satellite link has a lower metric than a fiber-optic line. On the other hand, if minimum ___48___ is the desired type of service, a fiber-optic line has a lower metric than a satellite line. OSPF allow each router to have several routing table based on the required type of service.
