Mods please look into this

HEY THERE! i intend to write the DSE entrance test, but when i went thru their old question papers i had no clue abt half the stuff in it ( illustrated as follows) . the r8 answers r given, but no idea hw one gets there.wud REALLY REALLY appreciate it if someone cud tell me. its URGENT!!!!

Consider a competitive exchange economy with 2 agents( 1 & 2) & 2 goods (X & Y) . Agent 1s endowment is(100,100) & agent 2s endowment is( 50,0). An allocation for agent i. is denoted (xi, yi) ,where xi is his allocation of X & yi is his allocation of Y. Agent 1s objective is to choose (x1,y1) to maximize his utility min{x1,y1}. Agent 2s objective is to choose (x2,y2) to maximize his utility x2+y2.

Answer the following questions on the basis of the above information:

1) an example of competitive equilibrium allocation for this economy is

a) (x1,y1) = (100,50) & (x2,y2) = (50,50)

b) (x1,y1) = (125,100) & (x2,y2) = (25,0)

c) (x1,y1) = (50,50) & (x2,y2) = (100,50)

d) (x1,y1) = (100,100) & (x2,y2) = (50,0)

ans: d.

2) an example of pareto efficient allocation for this economy is

a) (x1,y1)= (50,50) & (x2,y2) = (100,50)

b) (x1,y1) = (125,100) & (x2,y2) = (25,0)

c) (x1,y1) = (125,75) & (x2,y2) = (25,25)

d) (x1,y1) = (50,100) & (x2,y2) = (100,0)

ans: (a)

3) an example of a pair of competitive equilibrium prices( p1, p2) for this economy is

a) (1,0)

b) (0,1)

c) ( 1/3,2/3)

d) (2/3,1/3)

ans: ( 0,1)

4) suppose the govt. imposes a lumpsum tax of rs 50 on agent 1 and transfers the tax receipts as a lump sum subsidy of rs 50 to agent 2. After this wealth transfer, an example of a competitive equilibrium for this economy is: prices = (1/2,1/2) & allocation:

a) (x1,y1) = (100,100) & (x2,y2) = (50,0)

b) (x1,y1) = (50,50) & (x2,y2) = (100,50)

c) (x1,y1) = (0,100) & (x2,y2) = (150,0)

d) (x1,y1) = (100,0) & (x2,y2) = (50,100)

ans: (a)
