Looking for a job?

A Steel fixer, a painter, and an Electrician applied for jobs with a famous construction firm. From the information given below can you identify each worker's full name, job, and age?

Names: Ashraf, Nader, Maher.
Surnames: Fathy, Khedr, Badr.
Ages: 25, 30, 35

1. Fathy, the Electrician, is older than Ashraf.
2. Nader is the Painter.
3. The Steel fixer is 30 years old.
4. The youngest worker of the three is not called Badr.


  1. Dear Admin
    I'm very happy for visiting your blog. I have a blog on mathematics which publish it in 2 language. I want to visit my blog and send your comment about it.
    I have a question. May you link us?

  2. From the second clue we conclude the following:

    * Ashraf is not called Fathy, and he is not the electrician
    * Ashraf is not 35 years old and Fathy is not 25 years old

    From the third clue we conclude the following:

    * Since Ashraf is not the electrician, and Nader is the painter, then the electrician must be Maher, and Ashraf must be the Steel Fixer
    * Since Fathy is the electrician then Maher must be called Fathy

    From clue number 4, we conclude the following:

    * Fathy who is older than Ashraf must be 35

    From Clue Number 5, we conclude the following:

    * Since Badr is not 25 years old, and it is Fathy who is 35 then Badr must be 30, and he is the Steel Fixer
    * Nader must then be Khedr and he is 25 years old

  3. Late, but i solved it on my own i think:

    Ashraf Badr, Steel, 30
    Nader Kefre, Painter, 25
    Maher Fathy, Elec, 35

  4. Esmailifar,
    Your site looks extremely interesting to me, but I'll have to check it out further to decide about linking to it.

    I believe that most of my visitors are from the US and come here for the riddles, not necessarily the pure math. And so I'm not sure if they would be interested in your site.

    I'll have to think further on this.

  5. I got Maher Fathy-Electrician-35
    Nader Khedr-Painter-25
    Ashraf Badr- 30

    If you try it, it will work.
