Question

From 2009 subtract half of it at first, then subtract 1/3 of the remaining number, next subtract 1/4 of the remaining number, and so on, until 1/2009 number is subtracted. What is the final remaining number?

Answer 1

Answer:

Okay, I pick one zillion, zillion for short.

Add 10 to it

zillion + 10

minus 3 from it,

zillion + 10 - 3

zillion + 7

add 15 to it,

zillion + 7 + 15

zillion + 22

minus 5,

zillion + 22 - 5

zillion + 17

minus another 5,

zillion + 17 - 5

zillion + 12

add 20,

zillion + 12 + 20

zillion + 32

minus 6,

zillion + 32 - 6

zillion + 26

minus your original number

zillion + 26 - zillion

26

and you will have 26. Why?

I believe you can answer your own question now.

When I solve problems like this, and someone tells me to pick a number and keep it a secret from them, I always start with the number X.

Can you design your own riddle that includes you having them add the month they were born at one point, do assorted multiplication and division, then add the day of the month they were born, and eventually subtract the number they started with, and end up with their birthday?
