Question

if 54 X is multiplied of 3 where is a x is digit what is the value of x
​

Answer 1

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.

Answer 2

For 24x to be divisible by 3

2+4+x = 3,6,9,12,15

6+x = 3,6,9,12,15

therefore, x can be 0,3,6,9

there are two many answers because 6 can be added to

any other one digit to make it any other no. divisible by 3.
