Answer 2

Given: A number 8550*1 where * is unknown

To find: Least value of * such that it is divisible by 3

Explanation: For a number n to be divisible by 3, the sum of the digits of the number should be divisible by 3.

Here , number n given is= 8550*1

Sum of digits= 8+5+5+0+*+1

= 19+*

The sum of the digits is 19+ *. Now, nearest greater multiple of 3 is 21 for this number. For sum of digits to be 21:

19+* = 21

=> * = 21-19

= 2

Checking, the number becomes 855021 which is perfectly divisible by 3.

The least value of * in 8550*1 is 2 to be exactly divisible by 3.
