Tell the number what audience left! TRICK (2)

Tell audience to take any number (better 4 digit or 5 digit) then tell to add each number. then subtract the sum by original (first number) number.

in answer strike out any digit let tell the remaining digits. 

magician tells the struck out number.

Example : (1)

Audience takes 54695

5+4+6+9+5 = 29

then subtracting 29 by original number 

54695

-     29

54666

now if audience struck out the digit 5 and he/she tells 4666

Magician code: then use the formula make 9 and forget, 

now audience told 4666, here 6+6+6 = 18 (magician is to be fast in making total as 9 or 9th multiple such as 9, 18, 27,54 .....)

forget 18, remaining is 4 then subtract 4 by nearest 9th multiple i.e 4-9 = 5 

so audience struck out number is 5

Example : (2) 

Audience takes 8956

8+9+5+1 = 23

then subtracting 29 by original number 

8951

-   23

8928

now if audience struck out the digit 2 and he/she tells 898

Magician Code is : in audience answer 9 is exists just forget, then 8+8 = 16, nearest 9th multiple is 18, so 18-16 = 2

here audience struck out number is 2

Example : (3) 

Audience takes 6031

6+0+3+1 = 10

then subtracting 10 by original number 

6031

-   10

6021

now if audience struck out the digit 3 and he/she tells 021
 just take 0+2+1 = 3 then 9-3 = 6

here audience struck out number is 6
