Which one of the following numbers is exactly divisible by 11?
Answer: Option
Explanation:
(4 + 5 + 2) - (1 + 6 + 3) = 1, not divisible by 11.
(2 + 6 + 4) - (4 + 5 + 2) = 1, not divisible by 11.
(4 + 6 + 1) - (2 + 5 + 3) = 1, not divisible by 11.
(4 + 6 + 1) - (2 + 5 + 4) = 0, So, 415624 is divisible by 11.

@Arjun.
You are wrong.
EX- if you take 209/11.
Then your logic is wrong.
Because 2+0+9=11, and 11/11=1.
And I request you don't post wrong information because many peoples are confused with this type of example.
Hope you understand.

It is the principle for dividing any No. by 11.
If the difference between odd & even places No. comes 0 or 11 or multiple of 11 i.e. 22, 99, 121 etc. Then the whole No. will be divided by 11.
For example we also have principle for dividing any No. by 2. i.e.the unit place No. is divided by 2 that means the whole No. is divided by 2.
