Question

divisibility rule for 11

Answer 1

The sum of the even digits is subtracted from the sum of the odd digits. The result is either 0 or 11,if so the number is divisible by 11.

Example : 
i) 292215
ii) 760672 
Explanation : 
i) 292215 
By rule, (9+2+5) - (2+2+1) = 11 
ii) 760672 
By rule, (6+6+2) - (7+0+7) = 0 
Both the numbers can be divided by 11.

Answer 2

divisibility rule for 11 is:-

take a no. for ex:- 1364 
sum 1st and 3rd digit(odd digit) 1+6=7
then sum 2nd and 4th digit(even digits) 3+4=7
and then sub it.  i.e   sum of even digits - sum of odd digits = multiplier of 11.
                                                      7  -  7  =0
  hence its divisible by 11.
