  1. Oh, c’mon! The answer is intuitively obvious to the casual observer!

    Why, yes, I AM an engineer. Thank you.

    (Not my words, at the top. A great mathematician wrote this, in the margin, about the proof of one of his world-shaking equations, and it was 100 years before someone proved it. . .)

  2. My son is in the 4th grade and I think he could solve that. It’s a simple algebra problem. GOT IT has it right.

  3. Any non-moron should be able to figure that out.

    If that is how this company recruits “engineers”, I’m very concerned about the quality of their product(s).

  4. Actually 01-876-8000 is not right because it’s not a valid phone number which means there has to be some other puzzle involved which was the point, to weed out the people who can’t solve it. Personally I want to know where Scott came up with 314–596–2487. He either made up his answer, or solved it.

  5. 01876 192 000

    the area code 01876 is for lochmaddy on a little island called North Uist off the western shore of scotland…

    I think Scott gave us his real phone number, and Infidel spends too much time listening to oldies.

  6. Scott didn’t give you his number. He’s in Oklahoma and that area code is for the St. Louis area. A quick reverse phone look-up says it’s an unlisted suburban St. Louis landline.

  7. A very innovative advrt. Had it intended effect. It broke through the clutter and also lets the applicants know that they need to go prepared. Engineers who strive for creativity and innovation will enjoy working in this company.

  8. An easy one to figure out. Absolutely love the idea though!

    01 <– area code
    Ysq –X = (30 x 30) – 24 = 876
    (Ysq – 10sq) x 10 = ((30 x 30) – 100) x 10 = (300 – 100) x 10 = 200 x 10 = 2000

    So, we got 01 876 2000

    Awesome job app!

  9. who ever wrote this equation obviously did have the right answer but the equation is written in a confusing way. There are three different parts separated by dots.

    You cannot have dots to express multiplication in algebra.

    First section is 01
    Second section the answer is 876
    third section the answer is 8000

    the phone number is 01.876.8000

  10. The required telephone number is 01.876-8000.
    The actual phone number belongs to McKinsey & Company, a top management consultancy firm
    that posted the advertiesement.
    Here is their address:
    McKinsey & Company Switzerland
    Alpenstrasse 3
    8065 Zurich
    phone: +41 44 876 8000
    01.876.8000 is the phone-number for local calls

  11. @JM That number that @Scott shows looks somehow like Pi, but isn’t.

    3 14–596–2487.
    3.1415926535

  12. Whoa my real answer was off. I thought the x10 should equal 240. (I dreamed up the last 0 somehow and wrote 2400. Note: don’t do math at 3am.)

    The last part was confusing. From the correct answer, I think the last part should have been written:

    10(y^2-10^2)
