about how many people are in the world
You got 38 right.
138 questions right and 12 questions wrong
You'd be 100% right.
To get 90% you have to get 13 and 1/2 questions right.
No one person, but many. It's a way of sharing knowledge across the world. Contributors are fed questions. If you feel you have the knowledge to answer, you may do so. Others may disagree and modify the answer.
Many websites have user-compiled lists of general knowledge questions. There are also many books containing such lists, such as "Pub Quiz" compilations and other similar books. Some examples of websites include "Challenge the Brain" and a blog called "General Knowledge Questions and Answers"
I'm unable to determine how many questions you got right without additional context or information about the questions and your answers. If you provide the details, I can help you assess your performance.
