#25. More brain teaser games for job interviews

Let’s exer­cise our frontal lobes (that deal with plan­ning, among oth­er things), and pari­etal lobes (cal­cu­la­tions) with some quick brain teas­er games of the kind often used in job interviews.

Please try to guess the answers to the ques­tions below (you don’t need to know, or research, the right answer, sim­ply try to “guessti­mate” an appro­pri­ate range).


1) How many golf balls can fit in a school bus?

2) In 1999, how were these baby boy names ranked by pop­u­lar­ity: Kevin, Jose, Hugh.

3) What is the weight of a large com­mer­cial airplane?


1)  About 500,000, assum­ing the bus is 50 balls high, 50 balls wide, and 200 balls long.

2) Rank­ings of baby boy names in 1999, accord­ing to Social Secu­rity Admin­is­tra­tion: 1. Jose (#30), 2. Kevin (#32), 3. Hugh (#830).

3) For a Boe­ing 747:
– Emp­ty: around 400,000 pounds (lbs), or 181 met­ric tons
– Max­i­mum Take­off Weight: around 825,000 pounds, or 374 met­ric tons
– For con­text, the weight of an emp­ty Hum­mer is 8,600 pounds.

    1. 30 pairs
    2. Bar­bara, Emily, Amber, Tracy
    3. Kevin, Jose , Gary, Hugh
    4. 4 thou­sand tons

    30 pairs of shoes? Is that a misprint?

  3. Alvaro on October 19, 2006 at 6:57

    1) We don’t know how many pairs you have had :-)

    2) Rank­ings of baby girl names in 1999:
    Emi­ly #1
    Amber #41
    Bar­bara: #475
    Tra­cy #700

    Rank­ings of baby boy names in 1999:
    Jose #30
    Kevin #32
    Gary #290
    Hugh #830

    3) For a Boe­ing 747:

    Emp­ty: around 400,000 pounds (lbs), or 181,000 met­ric tons
    Max­i­mum Take­off Weight: around 825,000 pounds, or 374,000 met­ric tons

    The weight of an emp­ty Hum­mer is 8,600 pounds

    Elona, well, I guess it depends on Adam’s age, shop­ping habits…and gender :-)

    How many pairs did you expect Adam to have? 100 — 12?

    I’m a 29 year old male, and I guessti­mate I’ve had about 40 shoes in my life (that’s 20 pair). I have about 6 to 8 now, and I only wear one pair. But I’ve had all of them (except the ones I’m wear­ing now) for a num­ber of years. I wore one pair of shoes — and only one — for a total of 7 years. My $40 Nike High Tops.

    Just a remark: 400,000 pounds is about 181,000 kg, which is 181 met­ric tons. 

    And with an inac­cu­rate num­ber like this, you should real­ly round off the con­vert­ed val­ue even more, to sug­gest 400,000 lb ~= 200,000 kg.

  7. Mitch on January 6, 2008 at 4:11

    - about 50
    — Emi­ly, Amber, Tra­cy, Barbara
    — Hugh, Jose, Gary, Kevin
    — 100,000 kg

    Those are my guesstimations.

  8. Jen on February 14, 2008 at 12:29

    Lol, I guessti­mate that I’ve had about 200 shoes… they said shoes, not pairs, I’m 28 which is almost 30 (ugh), at least a 3 pair AVERAGE per year (if not more)… approx. 200, maybe more.

  9. Alvaro on February 14, 2008 at 8:48

    May I observe some gen­der dif­fer­ences, perhaps? :-)
