You can, in this way: First Comment You can, in this way: First (from the first digit), divide the no: into groups of 2. Eg: 62 34 56 78 98 76 54 55 55 48 Then, add them up. Eg: 62 + 34 + 56 + 78 + 98 + 76 + 54 + 55 + 55 + 48 = 616 If the sum is more than 100, repeat step 1 and 2. Eg: 6 16 6 + 16 = 22 If the sum obtained is divisible by 11, then the initial no: is divisible by 11. Reply
