Question

If 24x is a multiple of 3 wher x is a digit what is the value of x? Scince 24x is a multiple of 3 its sum of digits 6+x is a multiple of 3 so 6+x is one of these number 0 3 6 9 12 15 18 ....But since x is a dighit can only be than 6+x=6 or 9 or 12 or 15 Ther fore x=0 or 3or 6 or 9 Thus x can have any of four different values

Answer 1

ANSWER
Since 24x is a multiple of 3, its sum of digits 6+x is a multiple of 3;
So, 6+x is one of these numbers: 0,3,6,9,13,15,18,….
Since x is a digit, it can only be that 6+x=6 or 9 or 12 or 15.
Therefore, x=0 or 3 or 6 or 9.
Thus, x can have any of four different values.
