a) Ask the people to take the number of the month in which they were born (January is 1, February is 2, December is 12 and so on…)
b) Next, ask them to double the number c) Add 5 to it d) Multiply it by 5 e) Put a zero behind the answer f) Add the date of birth (If a person is born on 12th March, he must add 12)
THE SECRET !! From the answer that you get from each member of the audience : • Mentally subtract 50 from the last two digits, (the number that is left on subtracting 50 is the date on which he is born !) • Subtract 2 from the remaining number. (the number that is left on subtracting 2 is the month number on which he is born)
Now, let us see how to deduce his date of birth from 770
7
70
2
50
5
20
From the last two digits, we subtract 50 and get the DATE as 20 From the remaining number we subtract 2 and get the MONTH as 5 Thus, the date is 20 and month is 5. It is 20th May The technique is verified
