I have a question, please help me

Since you know that "if I give him money, he will not pay it back to me, and he has not paid back the money he has received from others before", then it is better not to lend him money. Just find a reason to refuse, such as the money in the hands of the parents and waiting for .......

You don't want to hurt his face, it seems that it can't be avoided now, if you don't lend him money, it will hurt his face, and when you lend him money to collect debts, it will hurt his face. One is a minor injury, the other is a major injury; So, it's better not to lend it to him.

It is unreliable to expect him to introduce you to a girlfriend, first of all, he may not want to introduce you to a girlfriend at all, and his purpose is to lend you money. Second, you lied to him, saying that "there is a second-hand house, two bedrooms, one living room, one kitchen and one bathroom", this way of making friends based on lies is unreliable.

In short, your way of making friends needs to be well adjusted, otherwise you will take a lot of detours and get half the result.

Tell him that he has tried his best to raise it, but he can't. Of course, you can't borrow it, and he just wants to borrow money when he introduces you to a girlfriend. The typical characteristic of this kind of person is to take an acquaintance under the knife, make you embarrassed not to lend him money, and then use various reasons to prevaricate when he asks for it.

If you don't believe it, you can try it, you say that if you can't raise it, he will reduce the amount. Don't lend him a penny!

You can't lend him money, let alone ask him to introduce a girlfriend. The former is small**, and the latter is large**.

There are two possibilities, you lend it to him and he doesn't pay it back, and you turn your face with him!

You don't borrow, he's not happy, he's turning against you!

Anyway, you have to turn your face, you choose!

You ask a good friend to borrow something valuable, such as a car or something, drive him up for a meal, and as soon as he says money, you say... I bought a car, but I'm embarrassed, because I'm looking for someone, let him introduce you.

You can tell him that you have something to do with your money at home.

As for a girlfriend, you can find it yourself.

50,Least common multiple of 30 = 150

Set: The diameter of the pool is 150x cm

Then: Dad will have 2 footprints every 150cm (not counting the footprints at the beginning and end of the 150cm), and there will be a total of 2x footprints when running down in one lap;

Zhang Ming will have 4 footprints every 150cm (not counting the footprints at the beginning and end of these 150cm), and there are 4x footprints in a lap;

And every 150cm of the beginning and end of the footprints, a total of x.

So: 2x+4x+x=1099

The diameter of the x=157 pool is: 150*157=23550cm=m.

Xiao Ming 0 30 60 90 120 150

Daddy 0 50 100 150

It can be seen that there are 7 footprints of 30 50 60 90 100 120 150 every 150 meters.

1099 7=157, pool circumference = 157 150 = 23550 cm= m

Pool diameter = meters.
