What would be the remainder when the sum of a 2 digits no. And the no. Obtained by reversing its digits is divided by 11?
2-digit number:: 10t+u
reverse number:: 10u+t
==========
(10t+u + 10u+t)/11 = (11t + 11u)/11 = t + u
-------
what would be the remainder when the difference of 3 digit no and the no obtained by reversing the digit is divided by 99 ?
3-digit number:: 100h + 10t + u
number reversed:: 100u + 10t + h
======
Remainder-- ???
100h+10t+u - (100u+10t+h) = (99h - 99u)/99 = h-u
