Question

If [6x23] is a number divisible by 9, then the least
value of X is:​

Answer 1

Answer:

So for a number to be divisible by 9, the sum of the digits should be divisible by 9.

So, 6+x+2+3= multiple of 9.

Step-by-step explanation:

6 + x + 2 + 3 = 11 + x

The closest multiple of 9 greater than 11 is 18.

So, 11 + x = 18

x = 18 - 11

x = 7

Thus, the minimum value of x should be 7.
