Detailed Solution

Concept- A number is divisible by 99 if and only if the number is divisible by both 9 and 11. A number is divisible by 9 if and only if the sum of digits in it is divisible by 9 and a number is divisible by 11 if and only if the difference of sum of odd digits and even digits is divisible by 11 or giving answer 0.
Checking for all numbers which are divisible by 9,
As we can see, 3572404 is not divisible by 9 it is not divisible by 9. Therefore, checking for divisibility by 11 we get:
Since 114345 is giving a difference as 0 it is divisible by 11.
