In a group of 200 people, 120 like reading, 80 like writing, and 50 like both. How many people like only writing?
Step 1: Identify the total number of people who like writing, which is 80.
Step 2: Identify the number of people who like both reading and writing, which is 50.
Step 3: To find the number of people who like only writing, subtract the number of people who like both from the total number of people who like writing: 80 - 50.
