The tree adds the digits of 9,87,654 step by step until one digit is left. What is the SMALLEST number you must ADD to 9,87,654 to make it divisible by 9?

Question

Accepted Answer

6. The digit sum is 39, then 3 + 9 = 12, then 1 + 2 = 3. So 9,87,654 leaves remainder 3 when divided by 9. Adding 9 - 3 = 6 gives 9,87,660, whose digit sum is 36. (3 is what you would SUBTRACT.)
