Which of the following numbers is not divisible by 11?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 2763.
Divisibility rule of 11:- A number is divisible by 11 if the difference between the sum of the digits in the odd places and the sum of the digits in the even places is either 0 or a multiple of 11
Option 2:- 2763
Sum of even digits = 7 + 3 = 10
Sum of odd digits = 2 + 6 = 8
Difference = 10 - 8 = 2 [not divisible by 11]
Thus, only Option 2 is not divisible by 11
