Given:

Number 98181*6

Completely divisible by 9

To Find:

Smallest whole digit number in place of *

Solution:

The divisibility rule of 9 states that ''if the sum of digits of any number is divisible by 9, then the number is also divisible by 9.''  

Now let us add the digits of the given number

⇒98181*6 = 9+8+1+8+1+*+6

             =33+*

∴ 33 is not divisible by 9

The next number divisible by 9 is 36.

∴ The smallest whole digit number in place of * is 3.

Hence, the smallest whole digit number in place of * can be 3
