Question

My co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004. How many different ones digits are possible in numbers that Larry likes?

Answer 1

There must be infinitely numbers different ones digits are possible in numbers that Larry likes.

Explanation:

Given that my co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004.

To find that how many different ones digits are possible in numbers that Larry likes:

From the given "Larry only likes numbers that are divisible by 4."

There are many numbers with one digits in the real number system that could be divisible by 4 .

We cannot say the count,so it is infinite.

Hence there must be infinitely numbers different ones digits are possible in numbers that Larry likes
