Answer:
(a) We know that a number is divisible by 11 if the difference of the sum of the digits at places and that of even places should be either 0 or 11.
Therefore, 928389 Odd places = 9+8+8=5
Even places = 2+3+9=14
Difference = 25-4=11
(b) We know that a number is divisible by 11 if the difference of the sum of the digits at odd places and that of even places should be either 0 or 11.
Therefore, 869484 Odd places = 8+9+8=25
Even places = 6+4+4=14
Difference = 25-14=11
Answer:
(a) We know that a number is divisible by 11 if the difference of the sum of the digits at places and that of even places should be either 0 or 11.
Therefore, 928389
Odd places = 9+8+8=5
Even places = 2+3+9=14
Difference = 25-4=1
(b) We know that a number is divisible by 11 if the difference of the sum of the digits at odd places and that of even places should be either 0 or 11.
Therefore, 869484
Odd places = 8+9+8=25
Even places = 6+4+4=14
Difference = 25-14=11
