What is the smallest number which can be added to 9454351626 so that it becomes divisible by 11?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6.
Divisibility rule for 11 = sum of digits at odd numbers - sum of digits at even numbers should be 0 or divisible by 11
Given number = 9454351626
The sum of digits at odd places = 25
The sum of digits at even places = 20
Difference = 5
Hence, 11 - 5 = 6 must be added to the number for it to be divisible by 11.
