Question

In a House party organised by Connor he ordered pizzas having a total of $222$ slices. Each guest ate $3$ slices of pizza. Was there any slice left?

• A. Yes
• B. No

Answer 1

The correct option is B No

No, there were no slices left because $222$ is completely divisible by $3$.
we can check it by applying divisibility of $3$ i.e if sum of digit of number is divisible by $3$ then the number is divisible by $3$.
So, $222=2+2+2=6$. which is divisible by $3$.
