hey for 30, just do the same maximisation problem you solved for question 27 but now put the max problem in the perspective of consumer 2 .. and then subtract from the resource to get consumer 1s consumption. for consumer 2, its a normal case of substitute goods so take p1>p2, p1<p2 and p1=p2 and solve for competitive eqbm.
Can you share your approach for 29? how did we get root 2?
