The Case of the Missing Digit

The Case of the Missing Digit

A friend of mine asked me to write down any multidigit number. But, he put a condition, the

number should not end with a zero.

I put down the number 96452

Then he asked me to add up the five digits and subtract the total from the original number.

I did and here is what I got:

96452 – 26 = 96426

He then asked me to cross out any one of the five digits and tell him the remaining numbers. I

crossed out the 2 and told him the rest of the digits. I neither told him the original number nor

what I had done with it. Yet ‘pop’ he told me the exact number I had crossed out.

How did you explain it?
