4．甲、乙两人沿铁路线相向而行，速度相同．一列火车从甲身边开过用了6秒，4分后火车又从乙身边开过用了5秒，那么从火车遇到乙开始，再过多少分甲、乙两人相遇？

答案

一、填空题：

1．10

原式=[240-（0．125×76+0．125×24）×8]÷14

=[240-0．125×（76+24）×8]÷14

=[240-100]÷14

=10

2．20

由于千位相加不向前进位，所以千位数字“我”只能是1或2。

若“我”是2，则千位上的“数”是9，个位上的“学”是4，并且个位相加向十位进1；从十位数字看，“爱”是7，并且十位相加向百位进1；再看百位，7+5=12，加上进位1得13，百位上的“学”得3与“学”是4矛盾，所以“我”不是2。

若“我”是1，则个位上的“学”是3，并且个位相加向十位进1；由于百位结果是3，必然百位相加向千位进1，因此千位上的“数”是9，这样十位上的“爱”是7，所以1+3+9+7=20。

3．89

由于这个数除以9余8，除以6余5，根据余数与除数差1的关系知，这个数加上1必能被9与6整除，再由已知这个数加上1就能被5整除知，这个数必是9、6、5的公倍数少1，9，6，5的最小公倍数是90，符合条件的最小自然数是89。

4.361

一本书从第1页至第9页，共用9个数码；第10页至第99页，共用2×90=180个数码；还剩数码975-9-180=786个，786÷3=262，即从第100页到第361页，共用数码786个，所以这本书共有361页．

5．（1）666；（2）1800；（3）C组，334

B组数的排列规律：依次用3乘以1、2、3、4…的积减去1，有

3×1-1=2，3×2-1=5，3×3-1=8，3×4-1=11，…

1997÷3=665…2，即B组中有666个自然数．

A组数的排列规律：第2、4、6、8、10…个数分别是6的1、2、3、4、5…倍，所以第600个数是6的300倍，即为1800．

C组数的排列规律：第1、3、5、7、9…个数分别是3的1、3、5、7、9…倍，第2、4、6、8、10…个数分别是前一个数加1得到的．

1000÷3=333…1，所以1000是C组里的第334个数．

6．140

由于1560=3×5×8×13，根据“n个整数之积一定，则这n个整数越接近，其和越小”，所以它的棱长之和最少是：

（10+12+13）×4=140

二、解答题：

1．14岁

由于小明妈妈与小明的年龄差是不变的，于是可以知道小明去年的年龄是：

26÷（3-1）=13（岁）

所以小明今年是14岁．

另解：设小明今年x岁，小明妈妈今年是（x+26）岁，列方程得

x+26-1=3（x-1）

解方程得2x=26-1+3

x=14（岁）

2．1小时

3．21元

甲、乙、丙三种糖混合后的平均价是：

（14×4+10×3+8×5）÷（4+3+5）

=126÷12

=10.5（元）

买2千克混合糖果的价钱是：

10.5×2=21（元）

4．20分

甲、乙两人沿铁路线相向而行，速度相同，从甲身边开过用了6秒，从乙身边开过用了5秒，说明火车与甲是同向而行，与乙是相向而行，于是

甲行6秒的路程+火车车长=火车行6秒的路程

火车车长-乙行5秒的路程=火车行5秒的路程

由此知，火车行1秒的路程等于每人行11秒的路程，即火车的速度是人行速度的11倍，火车从甲身边开过到与乙相遇用了4分，这段路程让人步行需要4×11=44（分），由于在火车行驶4分/里，甲向前行了4分，实际余下的人步行需44-4=40分，现这40分的路段由甲乙两人相向而行，且速度相同，所以还需40÷2=20分相遇．
