4.
(b) 100001
7) SA27355
(a) 86611291
d) 7023643
(el 58334661
4) 602111213​

Answer 1

Step-by-step explanation:

If the difference of the sum of its digits at odd places and sum of its digits at even places is either 0 or multiple of 11 then the given number is divisible by 11

83721

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

Sum of the digits at even places =2+3=5

Difference of the two sums =16−5=11

∴83721 is divisible by 11
