MIND READERS PARADOX
You can simply follow this MIND READERS PARADOX trick to challenge your friends
MIND READER asks a man in his audience to
think of a number, multiply it by 5, add 6, multiply by 4,
add 9, multiply by 5, and state the result.
Mind Reader subtracts 165 from this result, gets 1200, knocks off the
two zeros, and tells the audience that 12 was the number he thought of.
For example
- 12*5=60
- 60+6=60
- 66*4=264
- 264+9=273
- 273*5=1365
- 1365-165=1200
- 1200/100=12
How did he got it correct
Say a the number he thinks
- 5*a=5a
- 5a+6=5a + 6
- 4(5a+6)=20a + 24
- (20a + 24)+9=20a + 33
- 5(20a + 33)=100a + 165.
- 100a+165-165=100a
- 100a/100=a
