Question 1160562
C is correct


Check digit can be calculated by the following way:

step 1:

Add all the digits except the check digit that is the last digit on the right side.

             {{{Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3}}}

             {{{Total = 47}}}

step 2:

     Add the digits at odd starting from left, double this amount and finally add it with the total from step 1.
             = {{{0 + 4 + 7 + 3 + 1 + 3}}}

     =>{{{sum=18}}}

      Doubling the sum {{{2*18 = 36}}}

     Adding it with the total from step 1, we get

        {{{Total = 36 + 47}}}

        {{{Total = 83}}}

 Subtract the last digit of the total from step {{{2}}} with {{{10}}}, and this will be check digit.

        {{{Check _Digit  = 10 - 3}}}

        {{{Check _Digit  = 7}}}


answer: C. {{{7}}}
