Perform this calculation in your head, mentally adding the numbers as quickly as you can. Start with 1000 and add 40. Now add 1000. Add 30 to that, then add another 1000. Now add 20 to that result. Add another 1000 and finally, add 10 to that. What is the total?

4,100. If you got 5,000 you’re not alone. 96% of test subjects get the wrong answer.

Mario’s Racing Grandma

Mario is testing out a new car at the racetrack. His grandmother took it for a mile lap and averaged 30mph. How fast does Mario have to drive in the second lap to average 60mph for the two miles?

Show the answer »

90mph is an alluring answer, but it’s impossible. At 90mph the second lap would take 40 seconds. If Grannie’s first lap at 30mph took 2 minutes, traveling 2 miles in 2 minutes and 40 seconds is an average speed of 45mph. Traveling an average speed of 60mph for 2 miles would take 2 minutes and since the grandma’s lap took all of those 2 minutes, even if Mario could break the sound barrier he wouldn’t be able to average 60mph.

Have No Face

I turn my head and you may go where you want.
I turn it again, you will stay till you rot.
I have no face, but I live or die,
By my crooked teeth.

What am I?

Wolves and Owls

You are in the woods with owls and wolves. There are 22 eyes and 32 legs. How many owls and wolves are there?

Show the answer »

5 owls and 5 wolves, (not 6 owls because 2 of the eyes and legs are yours).2 * owls + 2 * wolves = 20 eyes
2 * owls + 4 * wolves = 30 legs
owls + wolves = 10 eyes → owls = 10 – wolves
owls + 2 * wolves = 15 → 10 – wolves + 2 * wolves = 15 → wolves = 5
owls + 5 = 10 → owls = 5

5 owls and 5 wolves, (not 6 owls because 2 of the eyes and legs are yours).

2 * owls + 2 * wolves = 20 eyes
2 * owls + 4 * wolves = 30 legs
owls + wolves = 10 eyes → owls = 10 – wolves
owls + 2 * wolves = 15 → 10 – wolves + 2 * wolves = 15 → wolves = 5
owls + 5 = 10 → owls = 5
