Question

Now you try and change these numbers into special numbers —

273

Short Note

Solution

Given number is 273

  • Its reverse is 372
    Now 273 + 372
    = 645

But this is not a special number so we proceed to the next step.

  • The reverse of 645 is 546
    Now, 645 − 546
    = 99

As the reverse of 99 is 99 again.

Thus, it is a special number.
