Q. 3. If 24x is a multiple of 3, where x isa digit, what is the value of x?20Since 24x is a multiple of 3, its sum oftsle8lydigits 6 +x is a multiple of 3; so 6 +x is one ofthese numbers: 0, 3, 6, 9, 12, 15, 18, .Butsince x is a digit, it can only be that 6 + x=6 or9 or 12 or 15. Therefore, x -0 or 3 or 6 or 9.Thus, a can have any of four different values.)
