Question

Test the divisibility of the following number by 11.​

Answer 1

To check the divisibilty of number by 11 , first find the sum of odd digits and even digits of that number and then subtract the sum of even from the sum of odd. If the difference is 0 or a multiple of 11 then the number is divisible by 11 . Example- 121
Sum of digits at odd places = 1+1 =2
S um of digits at even places =2
Sum of digits at odd places - Sum of digits at even places= 2-2=0
So , 121 is divisible by 11.

Answer 2
