Microsoft recruitment questions (basic questions)

I recently went online and saw Microsoft recruitment questions and basic questions.
I found that my IQ is low. The questions are as follows:
Basic Question type (note: this type of question type is relatively simple)

1. It takes an hour to burn an uneven rope from the beginning to the end. Now there are several ropes of the same material. How can I use the burning method to time the rope for an hour and 15 minutes?
2. You have a bucket of jelly, including yellow, green, and Red. Close your eyes and capture two of the same colors. You can determine whether you have two joos of the same color.
3. if you have an infinite amount of water, a 3-litre lift, a 5-litre lift, the two are not in the same shape, how can you accurately claim 4 liters of water?
4. a fork in the road leads to honest and lying countries respectively. There are two people who know that one is honest and the other is lying. Honest countries always tell the truth, and lie countries always lie. Now you are going to lie to the country, but you don't know which path to take. You need to ask these two people. What should I ask?
The first ball is a balance, and now we know that only one ball is different from the other. Ask how to name it and use it three times to find the ball. What about 13? (Note that this question does not indicate that the weight of the ball is light or heavy, so you need to consider it carefully)
6. Draw 10 straight lines at nine points. Do you need to have at least three points on each line?
7. How many times are there when the hour, minute, and second hands of the clock completely overlap in the 24 hours of a day? What is the time? How did you calculate it?
