Question

Suppose that we have; $\frac{4K8}{3}=m$
In the equation above, $K$ is a digit in the three-digit number $4K8$, and $m$ is a positive integer. Which of the following could be the digit $K$?

• A. $1$
• B. $3$
• C. $4$
• D. $5$
• E. $7$

Answer 1

The correct option is B $3$

Question says that number $4K8$ is divisible by 3

For a number to be divisible by $3$, sum of digits of number should be divisible by $3$. Therefore sum of digits is $4+K+8=12+k$, So one value of $k$ is $3$, because $15$ is divisible by $3$
