Question

what can be fill in place of x in 67x19 so the number can be divisible by 9.

Answer 1

we know that diviibility of 9 is if the sum of all the digits of number is 9 it is divisible by 9
Here all the digits add up to 23 , the nearest number is 27 which divisible by 9 . So add 4

Answer 2

Since we know that divisibility of 9 is if the sum of all the digits of a number should be 9 or multiple of 9.and
6+7+1+9=23.and 23 is not the multiple of 9 . the nearest multiple is 27.
therefore;
27-23=4.
hence; the value of x is 4.
