Sure, you can go ahead. I encourage discussions, would love to contribute a bit but I just hope they will remain discussions. It would be not-so-interesting for me to reply to posts like these - "Please provide solutions to Ques # X, Y, Z etc."

I tried to solve it but I'm not sure whether my solution is correct or not. Although I could guess the answers somehow.

i got (a) by differentiating utility function by q and deriving the demand curve.
finally it was like a monopolist question.

For ques 23 even I got the answer following your approach. But I'm confused because of screening. Do we have to consider the screening effect in this question? If yes then the answer will differ.

Thank you sir.
Sir if high type consumers are always going to choose (q-low, t-low), then how will the monopolist differentiate among the two types of consumers. And it's clearly mentioned in the question that the monopolist can observe both the types of consumers.

In Q 23, he can observe the type. So, he can offer different plans to the two types.
In Q 24, monopolist cannot observe the type. In this case, both the types will choose the (qL, tL).

I have provided solutions to both the questions in the video, please see it carefully.

Hey maecon, we get only one value of px/py.
Even for question 21 we get only one value.
