Final answer:
It would take 3 people 10 days to make 180 questions.
Step-by-step explanation:
In this question, we are given that it takes 2 people to make 120 questions in 10 days. We can use this information to find the rate at which each person makes questions by dividing the total number of questions by the total number of people and the total number of days. So, each person makes 120/2/10 = 6 questions per day.
Now, we are asked how long it would take for 3 people to make 180 questions. If each person makes 6 questions per day, then 3 people would make 3 * 6 = 18 questions per day. We can find the number of days it would take 3 people to make 180 questions by dividing the total number of questions by the rate at which the group of people makes questions. So, 180/18 = 10 days.
Therefore, it would take 3 people 10 days to make 180 questions.
