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.
Form the alternating sum of the digits.
415624 = 4-1+5-6+2-4
= 4+4-4-4
= 8-8
= 0

@ Ali
No its just for 11..
The difference b/w odd and even numbers total should be 0, 11 or multiple of 11 i.e. 22, 484 etc.

Take the number and add all the even positions of the number and odd positions of the number then subtract those two.

If sum of all digit will be divisible by 11, the answer will be correct.
Ans=D
4+1+5+6+2+4=22
22 is divisible by11.
Ans=D
4+1+5+6+2+4=22
22 is divisible by11.

2+3+5+6+4+1 = 21/11.
2+4+5+6+4+2 = 25/11.
3+1+5+6+2+4 = 21/11.
4+1+5+6+2+4 = 22/11 = 2 it is divisible by 11.
2+4+5+6+4+2 = 25/11.
3+1+5+6+2+4 = 21/11.
4+1+5+6+2+4 = 22/11 = 2 it is divisible by 11.

Odd position - even position.
If it is a case then 2nd option violates it.
Can anyone explain it clearly?
