Question

if 48x is a multiple of 3, where X is a digit, what is the value of x? ​

Answer 1

Answer:

X=3

Bcoz 483 is devided by 3 properly

Answer 2

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.
