68,717
3,882
2,010
all of the above
this is option​

Answer 1

Answer:

number is divisible by 11, if the difference of sum of its digits in odd places from the right side and the sum of its digits in even places from the right side is divisible by 11.

(i) 5918

Sum of digits at odd places = 5 + 1=6 and,

sum of digits at even places = 9 + 8= 17

Their difference = 17 – 6 = 11 Which is divisible by 11

5918 is divisible by 11.

(ii) 68, 717

Sum of digits at odd places = 6 + 7 + 7 = 20

and, sum of digits at even places = 8 + 1 =9

Difference = 20 – 9 = 11

which is divisible by 11

68717, is divisible by 11.

(iii) 3882

Sum of digits at odd places = 3 + 8 = 11 and,

Sum of digits at even places = 8 + 2 = 10

Difference = 11 – 10 = 1 Which is not divisible by 11

3882 is not divisible by 11.

(iv) 10857

Sum of digits at odd places =1 + 8 + 7 = 16

and, Sum of digits at even places = 0 + 5 = 5

Difference = 16 – 5 = 11

which is divisible by 11

10857 is divisible by 11.
