Question

What should be the value of * so that the number 2*345 is divisible by 9?

Answer 1

Value of * is 4

Explanation:

The criterion for divisibility by 9 is that , the sum of the digits of the number must be a multiple of 9,

Given number is : 2*345

adding the available digits other than * we have:

2+3+4+5= 14

The multiple of 9 close to value 14 is

`9\times 2`= 18

To get the sum 18 , we need to add 4 to 14.

So value of * is 4.

So the number is 24345

(cross check : `24345/9` = 2705)
