Answer:
If the difference of the sum of alternative digits of a number is a multiple of 11 or is 0 then that number is divisible by 11 completely.
98*0471
Sum of the digits in odd place = 1 + 4 + * + 9 = 14 + ?
Sum of the digits in even place = 7 + 0 + 8 = 15
Difference = 15 - 14 = 1
So, as mentioned earlier to make it divisible by 11 it should be either a multiple of 11 or 0 and the closest here seems to be 0. Thus we should be adding 1 to make it divisible by 11.
14 + ? = 14 + 1 = 15
Thus the difference is 15 - 15 = 0
