My question is: James and John combine their friends lists. James has 75 friends. John has 3 times as many friends as James. They share 25 friends. How many people are on the combined list? Your thoughts:

John has 75 * 3 = 225 people on his friends list. So that means there are 225 + 75 = 300 people on the list. So once you remove duplicates there are 300 - 25 = 275 people. The final answer: 275.
