An engineer, a mathematician, and a CPA each interviewed for a CFO opening and all three did equally well. So, in order to break the tie, the boss asked each one the same devious question, “What’s 2 + 2?”

The engineer responded quickly “4” - and was told to go home.

The mathematician thought about it and said, “It lies between 3.999… and 4.0001” - and was also let go.

The CPA thought about it for a few minutes, looked around, checked for any hidden microphones and then quietly asked, “What do you want it to be?” He got the job.

一名工程师、一名数学家和一名注册会计师分别参加了首席财务官职位的面试，三人的表现都一样好。所以，为了打破僵局，老板问了每个人同样狡猾的问题:“2 + 2等于多少?”

工程师迅速做出了“4”的反应，并被告知回家吧。

数学家想了想，说:“它介于3.999…和4.0001之间。”

会计师想了几分钟，环顾四周，看看有没有隐藏的麦克风，然后平静地问:“你想要多少?”然后他得到了这份工作。

Mother is 21 years older than her son.

In six years she will be five times older than her son.

Question: Where is Dad?

母亲比儿子大21岁。

六年后她将比她儿子大五倍。

问：爸爸在哪里?

Solution:

Age of son at this moment = x

Age of mother at this moment = y = x + 21.

Age of son after 6 years = x + 6

Age of mother after 6 years = x + 21 + 6

After six years mother is five times older than son = (x + 6) * 5

We solve this system of equations:

解：

此时儿子的年龄x

此时母亲年龄 y = x + 21。

六岁后儿子年龄 x + 6

母亲6岁后的年龄 x + 21 + 6

六年后，母亲比儿子大五倍(x + 6) * 5

我们求解这个方程组:

5 * (x + 6) = y + 6

5 * (x + 6) = x + 21 + 6

5x + 30 = x + 27

4 x = -3

x = - 3/4

At this moment son’s age is - 3/4 of the year, which is -9 months, which means at this moment daddy is on mother.

5 * (x + 6) = y + 6

5 * (x + 6) = x + 21 + 6

5x + 30 = x + 27

4x = -3

x = - 3/4

在这个时候，儿子的年龄是- 3/4，也就是-9个月，这意味着在这个时候爸爸在妈妈身上。

Once a Mathematician was giving an interview.

Interviewer : Suppose you had an urgent and important meeting in your office and you are late and running fast to reach the office as early as possible and at the same time you see a building caught by fire with some people in serious problem in that building.Then what will you do??

Mathematician: Mam I will help the people caught in fire in the building by calling fire brigade.

Interviewer: Ok, same question but now there is no fire in the building.

Mathematician: Mam , I will set fire in the building and then the solution of this problem became same as the previous one.

有一次，一位数学家在接受采访。

面试官：假设你在办公室里有一个紧急而重要的会议，你迟到了，赶紧尽可能早地赶到办公室，同时你看到一栋大楼着火了，大楼里的一些人都遭遇了严重的问题。然后你会做什么?

数学家：嗯…我会打电话给消防队帮助大楼里失火的人。

记者：好的，同样的问题，但是现在大楼里没有着火。

数学家：嗯…我要到大楼里放火，然后这个问题的答案就变成和前一个一样了。

A mathematician is waiting for his pregnant wife to give birth. His mother in law calls: “Is it a boy or a girl?”

The mathematician replies: True

一位数学家正在等待他怀孕的妻子生孩子。岳母打电话问:“是男孩还是（或）女孩?”

数学家回答:是的。

Married couple, dealing with an issue …

“You love your mathematics more than you love me!”

“Not so, darling, I love you much more.”

“Then prove it!”

“OK. Let R be the set of all lovable obxts…”

已婚夫妇，处理一个问题…

“你爱你的数学胜过爱我!”

“不是这样的，亲爱的，我更爱你。”

“那就证明它!”

“好吧。先令R是所有可爱东西的集合……”
