Divisibility rule of 11:
The divisibility rule of 11 says that the difference of sum of digits at odd position and sum of digits at even position should be either 0 or should be a multiple of 11.
In other words, start from last digit and keep on adding every alternate digit up-till extreme right , and let’s call this value sum1. Now, start from last second digit and keep on adding every alternate digit up-till extreme right , and let’s call this value sum2.
For divisibility of 11: sum1 - sum2 = 0 or multiple of 11
now assume that number is 3
6+2-5+3=0
it satisfied divisibility rule of 11
answer is 3
