Answer 1

The divisibility rule for 9 :

The sum of the number must divided by 9 .

Let's Check out :

7+3+4+9+a = 23+a

Now , the multiples of 9 :

9,18,27,36...

But it lies between 18 and 27 .

But in the Question it is being asked that you have to find the least value so , we will take 27 .

27 = 24+ a

27-24 = a

3= a

The least value of a is 3 .


The required number is 73593


73953÷9 = 8217 .
