Respuesta :

The cycling club is made up of 40 people.

How to find how many people belong to the club?

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%?

  • 100 × 12 ÷ 30 = 40

So the total number of members is 40 people.
