In the answer key, Correct Answer is Option(d): A is a liar, B is a Normal person, C is a truth teller.

Thanks for replying duck :)
I'm sorry I wasn't clear in my original post. I actually meant the 30th question in Part II, which is the 50th question in the paper:

[Amit Goyal]

Competitive equilibrium (Q 30):

Prices (1, 2)
A will demand (1, 2)
B will demand (3, 0)

@Duck:
How does on arrive at the contract curve for question 29?
Or rather, how does one prove that OPTION B is the contract curve?

[duck]

Hi.. :)

Agent 2's utilty can be written as (x+2y)^2 which is a monotonic transformation of (x+2y).
And Agent1's utility = (x+y)
Now, work out for the contract curve.
