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.

Divisibility rule:
Form the alternating sum of the digits.
415624 = 4-1+5-6+2-4
= 4+4-4-4
= 8-8
= 0
0 divisible by 11.
So Answer is 415624.

By sum of all digits can be divisible by 11 also we can calculate.
1. option sum is 21 so it is not divisible with 11
2. option not
3. option not
4. option sum is 22 is divisible by 11
So ans is 4.option
