Question

How many numbers less than or equal to 100 are divisible by either 2 or 3, but not by 4?

Answer 1

We are looking for numbers less than or equal to 100 that are divisible by either 2 or 3, but not by 4.

We have these numbers (n is an integer ≥ 0):

2 + 4n (0 < n < 24)--25 total

3 + 6n (0 < n < 16)--16 total

There are 41 total numbers.
