Questions & Step-by-Step Solutions
In a group of 150 people, 90 like reading fiction, 60 like reading non-fiction, and 30 like both. How many like only non-fiction?
Step 1: Identify the total number of people who like non-fiction, which is 60.
Step 2: Identify the number of people who like both fiction and non-fiction, which is 30.
Step 3: To find the number of people who like only non-fiction, subtract the number of people who like both from the total number of non-fiction readers: 60 - 30.
Step 4: Calculate the result: 60 - 30 = 30.
Step 5: Conclude that 30 people like only non-fiction.
