Question

What is the value of $x$ such that $23x$ is divisible by $5$?

• A. $3$
• B. $2$
• C. $5$
• D. $1$

Answer 1

Answer: (C)

$5$

We know the divisibility rule for $5$: The last digit is either $0$ or $5$.
So, $235$ is divisible by $5$, because the last digit is $5$.
Hence, the value of $x$ is $5$.

So, option C is correct.
