Write the number 1089 on a piece of paper in such a way that when the paper is placed upside down, the number looks like 6801. Before you begin the game tell your friend that this will be the answer to the puzzle. Now ask your friend to do the following: |
| Steps |
Example
|
| 1) Write down any 3 digit number which contains different digits in the hundred's and one's place. |
379
|
| 2) Reverse the above number. |
Reverse
of 379 is 973
|
| 3) Subtract the smaller number from the larger number. |
973
- 379 = 594
|
| 4) Reverse the answer of step 3 and add this number to the answer. |
495
+ 594 = 1089
|
| Have your friend announce the answer. Now hold up your prediction so that it reads 6801 (which is not the correct answer). Your freinds will laugh, but then you turn it over and give the correct result of 1089. | |
