Question

There is an international tennis tournament at your local stadium and Gemma has been selected to work as a ball girl.

Out of 225 applicants, 1 5 were successful.

Of the successful applicants, 20% couldn’t make all the training sessions and were discounted.

How many were selected to work at the tournament?

Answer 1

45 applicants were selected to work in the international tennis tournament at your local stadium, but just 36 (Gemma included) completed all the training sessions.

Explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of applicants to work in the international tennis tournament = 225

Number of successful applicants = 1/5 of 225

Number of successful applicants that couldn't make all the training sessions and were discounted = 20%

2. How many selected to work at the tournament?

For answering this question, we will make the following calculations:

Number of successful applicants = 1/5 of 225 (1/5 = 0.2)

Number of successful applicants = 225 * 0.2

Number of successful applicants = 45

Number of successful applicants that couldn't make all the training sessions and were discounted = 20% of 45

Number of successful applicants that couldn't make all the training sessions and were discounted = 0.2 * 45 = 9

45 applicants were selected to work in the international tennis tournament at your local stadium, but just 36 (Gemma included) completed all the training sessions.
