Question

if 3× 12 is a multiple of 9 and x is a digit then find the value of x​

Answer 1

Answer:

IF the sum of the digits of a number is divisible by 3 then the number is also divisible by 3

so the digits of the number 3x12 are 3,x,1,2

3+x+1+2=6+x

if we will substitute x=0 then

6+x=6+0=6 which is divisible by 3

therefore we can say that x=0

and the number will be 3012
