Divisibility rules(11)

Divisibility rule of 11:-

 Number=abcdef

                sum of odd places digits=b+d+f.

                sum of even plces digits=a+c+e.

       Differnce of these two =(b+d+f)-(a+c+e)

       should be divisible by 11(0,11,22 ........ ).  

         Ex-8294,

          Sum of odd places digits=4+2=6.

          Sum of even places digits=9+8=17.

      Difference=17-6=11,here difference is divisible by 11,so 8294 is also divisible by 11.
