IBM技术岗位笔试试题及答案

IBM笔试题（三）

PARTII 数列猜测 没有像考到19，21，那样的，因为只有4分钟20个题。
基本都是18，20，25这样的题。
It consists of number series. In some institutes alphabetical series is given instead of number series. I am having number series so I am sending that. Please go through the alphabetical tests also.
15. 30,28,25,20,34,28,? a:21
16. 4,8,16,32,64,128,? a:256
17. 8,16,24,32,40,48,? a:56
18. 13,11,14,12,15,13,? a:16
19. 6,18,36,108,216,648,? a:1296
20. 4,4,8,8,16,16,? a:32
21. 2,6,18,54,162,486,? a:1458
22. 4,20,35,49,62,74,? a:85
23. 10,18,15,23,20,28,? a:25
24. 4,10,8,14,12,18,? a:16
25 10,15,12,17,14,10,? a:16
个人觉得IBM好好准备下，还是可以考的。下面贴一个常用词汇表，IPAT总结就结束了，希望对大家有所帮助。我就把odd和even记反了，狂晕啊~~~~
clockwise，顺时针 counterclockwise，逆时针
exchange ,交换 catercorner,对角线
diagonal,对角线 perimeter,周长
rectangle,长方形, 矩形 square, 正方形
volume, 体积 remainder,余数
prime,质数 odd,奇数
even,偶数 periphery,外围
diameter 直径 radius　半径
fraction 分数 subtract 减法
cube 立方 dimension　维，尺寸，度

PartⅠ:
本部分计分方法为答对题数乘以1
给你一个矩阵： ㈠ ㈡ ㈢ ㈣ ㈤
1 a b c d e
2 b c a e d
3 c b e a d
4 c e d b a
5 e d a c b
回答以下问题。
问：⑴将第一行和第四行交换后，第一行第四个字母下面啲左边啲下面啲右
边啲字母係？
①a ②b ③c ④d ⑤e
⑵将所有出现在d左边啲字母从矩阵中删掉。将所有出现在a左边啲c字母
从矩阵中删掉。如果矩阵中剩低啲字母啲种类啲数目大于3，答案为原
矩阵中左上方至右下方对角线上出现两次啲字母。如果矩阵中剩低啲字
母啲种类啲数目小于或者等于3，答案为原矩阵中右上至左下对角线上
出现4次啲字母。
①a ②b ③c ④d ⑤e
P4
⑶将所有啲a用4替换，所有啲d用2替换，边一列啲总和最大？
①㈠ ②㈡ ③㈢ ④㈣ ⑤㈤
⑷从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个
①a ②b ③c ④d ⑤e
⑸沿第5列从上到下，接着沿第3列从下到上，接着沿第4列从上到下，接着
沿第1列从下到上，接着沿第2列从上到下，第一个出现5次啲字母係？
①㈠ ②㈡ ③㈢ ④㈣ ⑤㈤
⑷从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个
①a ②b ③c ④d ⑤e
⑸沿第5列从上到下，接着沿第3列从下到上，接着沿第4列从上到下，接着
沿第1列从下到上，接着沿第2列从上到下，第一个出现5次啲字母係？
①a ②b ③c ④d ⑤e
（请停止作答，等待提示翻到下一页）
第二部分：英文字母排序 时间25
个人心得：先把26个字母写一排在纸上，容易找规律些。可惜做到一半采用此法。
题信大至是：aabbcc 选下一个为d。当然有的不这么简单，有时跳了好多个，也有向前
或向后跳着的规律。所以先把26个字母写一排在纸上，容易找归率些。
第三部分：数学题时间35
繁琐的数学，最好不用计算器（只用了两次计算器），大致估算就可，这样节约时间
可惜还是没做完。
