Question

If 24X is a multiple of 3, where X is a digit , what was the value of X.​

Answer 1

Answer:

x=0,3,6,9

Step-by-step explanation:

the x can be 0,3,6,9

Answer 2

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, 12, 15, 18….

But since x is a digit,

it can only be that 6 + x = 6 or 9 or 12 or 15.
