4. Using this technique you can find out how many siblings/children a person has without him telling you ! Whenever you are in a party, picnic or a group- gathering you can impress many people using this technique You can try this stunt with your family members, friends, relatives etc.

5. © Dhaval Bathia Here are the steps : a)Ask the people to take the number of brothers they have. Only siblings (children born of same parents). No cousins. If they have no brother, take the value as zero. b)Next, ask them to add 3 to the number c) Multiply by 5 d) Add 20 e) Double the answer f)Add the number of sisters they have (if no sisters, take zero) g) Add 1 to the total to get the final answer After the steps are done, ask him to tell you the final answer. And lo ! Just by listening to the final answer you can tell his date of birth !!

6. © Dhaval Bathia THE SECRET !! From the answer that you get from each member of the audience : Mentally subtract 1 from the last digit to get the number of sisters he has. Subtract 7 from the remaining number to get the number of brothers he has. In this way you can find the siblings of anybody. You can also use this technique to find the number of sons and daughters a person has. Just substitute ‘son’ in place of ‘brother’ and ‘daughter’ in place of sister in the above technique.

7. © Dhaval Bathia Suppose a member of the audience had 3 sisters and 2 brothers This is how he would have worked out the steps: (A)Take the number of brothers = 2 (B) Add 3 to it = 5 (C) Multiply by 5 = 25 (D) Add 20 = 45 (E) Double it = 90 (F) Add the number of sisters that you have (3 sisters) = 93 (G) Add 1 = 94

8. © Dhaval Bathia Thus his answer would have been 94 Now, let us see how to deduce the number of his siblings from ’94’ 9 4 - 1 From the last digit, we subtract 1 and get sisters as 3 From the remaining number we subtract 7 and get brothers as 2 Thus, there are 2 brothers and 3 sisters ! The technique is verified ! (Note: the technique will not work if the number of brothers and sisters assumed is too big) 32 7

9. © Dhaval Bathia On similar lines, if the total was 82, 101 and 168 the answers would have been (1 brother, 1 sister), (3 brothers, zero sisters) and (9 brothers, 7 sisters) respectively. 8 2 - 7 1 1 1 10 1 - 7 1 0 3 16 8 - 7 1 7 9 With this technique you can predict the birth-dates of hundreds of people simultaneously.
