Ask your friend to guess a number between 1 to 9....
Ask him/ her to following calculation....
Step 1: Multiply the guessed number by 2
Step 2: Add 2 to the result
Step 3: Multiply the result by 5
Step 4: Add 5 to the result
Step 5: Multiply the result by 10
Step 6: Add 10 to the result
Ask the result...
The last 2 digits of result will be 60....
Subtract 1 from the first digit and that will be the number guessed by your friend...
Example..: let the guessed number is 3...
Then
3*2=6; 6+2=8; 8*5=40; 40+5=45; 45*10=450; 450+10=460;
Last 2 digit is 60...
first digit is 4 therefore guessed number is 4-1=3
Try it....Have fun...
