is exactly divisible by 11
5
6
7
8​

Answer 1

Answer:

A number is divisible by 9 if the sum of its digits is divisible by 9.

Now, Sum of the digits in given number is =6+7+3+0+1+2=19, which is not divisible by 9.

But, if we add 8 to this sum, it becomes 19+8=27, which is divisible by 9

So, the least number is 8 which should replace for ∗ in the given number. So, 6730182 is divisible by 9
