How does it work?
1. Guess any two digit number
Say,
xy (where x and y can be from 0,1,2…9)
So, number will be
(10x + y) ………(i)
2. Add two digits and subtract total from the original number
Add two digits,
(x + y)
Subtract total from the original number
(10x + y) - (x + y)
= 9x
So, considering x values 0,1,2….9
solution can be any number of,
0, 9, 18….81
In symbols, above numbers have same symbol, which comes in the ball!
