Question

If 3*12 is a multiple of 3 and x is digit, then find the value of x

Answer 1

Answer:

If 3*12 is a multiple of 3 then sum of 3,*,1 and 2 will be equal to a multiple of 3

Let * be X

3+X+1+2=6+X

If we take X as 0,3,6 or 9 them the sum would be a multiple of 3

Therefore the value of x can be 0,3,6 or 9
