Ask your friend to think of any lucky number (below 10)

Step 2:

Ask him to multiply with 10

Step 3:

Ask him to add 14

Step 4:

Ask him to subtract 8

Step 5:

Ask him to tell the result

Secret: Always you get 6 in the units place. The number before 6 is the lucky number.

	Step 1:	Let the lucky number be 3
	Step 2:	3 x 10 = 30
	Step 3:	30 + 14 = 44
	Step 4:	44 – 8 = 36
	Step 5:	36
	Step 6:	36
	Hence the money in your friend’s lucky number is 3

If you subtract 6, you get the lucky number.
