Answer 2

Answer:

Divisibility Principle of 11

If the difference, of the odd place digit

and even place digit from right of the

given number, is either O or divisible by

11, then the given number also divisible by

11

(i)22222

sum of odd places= 2+2+2=6

sum of even places= 2+2=4

difference = 6-4 = 2

Since the difference is 2, so we can say

the given number 22222 is not divisible

by 11.

(ii) 444444

sum of odd places= 4+4+4 =12

sum of even places = 4+4+4 =12

difference = 12-12-0

Since the difference is O, so we can say

the given number 444444 is divisible by

11.

(iii)379654

sum of odd places = 4+6+7=17

sum of even places =5+9+3 =17

difference = 17-17 =0

Since the difference is 0, so we can say

the given number 379654 is divisible by

11.

(iv) 1057982

sum of odd places = 2+9+5+1 = 17

sum of even places = 8+7+0=15

difference = 17-15 = 2

Since the difference is 2, so we can say

the given number 1057982 is not divisible

by 11.
