The cycling club is made up of 40 people.
<h3>How to find how many people belong to the club?</h3>
To find the number of people who belong to the club we must identify what information we have.
- We know that each person went on a trip at least once.
- On the first trip it was 50% of the members, while on the second it was 80%.
- Additionally, we know that 12 members went on both trips, meaning that 30% equals 12 people.
According to the above, we perform the following mathematical operation, rule of three:
If 12 members equals 30%, how many people equals 100%?
So the total number of members is 40 people.
