Two Hours Ago

If two hours ago it was as long after one o’clock in the afternoon as it was before one o’clock in the morning, what time is it right now?

Show the answer »

9pm (or 21:00). There are 12 hours between 1pm and 1am, so 6 hours after 1am is halfway. 6 hours + 1pm equals 7pm. In order for 7pm to be 2 hours behind the current time, it must be 9pm.

Sum of 22

Fill in numbers such that the sum of each 3-character row is 22 while the sum of all five numbers is 30.

a
b	c	d
e

Show the answer »

The problem works out to a set of three equations:
b + c + d = 22
a + c + e = 22
a + b + c + d + e = 30Solving for c = 14, leaving d = 8 – b and e = 8 – a. In other words, c must be 14, but the other two numbers just have to add up to 8. The requirement that they be unique rules out 4 + 4, so you’re left to choose from the following combations for b + d and a + e:
0 + 8
1 + 7
2 + 6
3 + 5

A Room With No Windows

You are in a room with no windows, doors or any exit. The only items are a mirror and a table. How do you escape?

Hint: This is not a typical brain teaser.

Show the answer »

Look in the mirror, then at the wall and back at the mirror to see what you saw. Use the saw to cut the table in half and join the two halves to make a whole. Put the “hole” on the wall and climb out.I know, it’s lame. I like to have brain teasers that you can realistically guess, but this one’s so popular, I feel an obligation to include it.
