Question

What is the value of $x$ such that $78x4$ is divisible by $8$?

• A. $1$
• B. $3$
• C. $6$
• D. $4$

Answer 1

The correct option is C $6$

We know the divisibility rule for $8$:
If the last three digits are divisible by $8$ or last three digits of the given number are zeros, then the number is divisible by $8$.
Here $7864$ is divisible by $8$, because the last three digits are divisible by $8$.
So,option C is correct.
