please help me on these question with explaination.

Perfectly competitive markets will result in productive efficiency as long as ()A. Firms face the same prices for capital and labour B. Firms minimize costs C. Consumer MKSs are equal D. Answers A & B O E. Answers A. B & C The PPF for an economy is given by Y =18-2X. Suppose 4 units of good X are produced in this economy. Then the production efficient amount of good Y in this economy is 04 8 10 12 Not enough information to determinelabour for good Y A Good Y Labour for good Y capita Good Y Capital for good Y Capital for good X Capital for goodY Capital for good X JA Good X Labor for good x labor Good X labor Labour for good x Point A is Point A is )C. Inefficient ()D. Equilibrium Allocationficient but not Productively Efficient E. Pareto Improving Productively Efficient and Allocatingly Efficient )A. Efficient Allocationly Efficient (B. Pareto Optimal )Productively Efficient Productively Efficient but not AllocationficientThe Production Possibility Frontier for an economy is given by I y 40751 If this economy is producing 10 units of good x, then its MRT is equal to ()A. 1/2 (\"3.1 r,/ 0Q: C, [L 10 Q E. 35 Consider an economy with two firms using Capital and Labour to produie output, and the MRTS for Firm A is greaterthat the MRTS for firm B. If Capital and Labour are the oniy Inputs to production. and you were to plot this situation in an Edgeworth Box (with Labour on the horizontal axis. and Firm 3'; origin in the too right], then 0 Hum A is productiveiyefficient, but Firm B is not (:1 The ailooation is beiow the Contract Curve C) The ailocatioh is above the Contract Curve (:2 Firm A is not profit maximising (:3 Not enough information determine Economy A has a PPI given by y - 10 - 2: and economy R has a PPF given by y = 20 - Which of the following statements is TRUC? Economy B can produce additional units of good x at lower opportunity cost than can economy A. Il. Economy A can produce additional units of good y at lower opportunity cost than can economy B. Ill. Consumers in economy A will consumer more good x than consumers in economy B. Ill only. Ol and II only Ol, II, and III. I and Ill only None of the statements are trueThere are two firms. One produces X and one produces Y and they have the following production functions: 1 2 1 2 Fl : K: L: and F3, : mg + Ly where K is capital and L is labour. Which ofthe following equations could represent an interior solution for the contract curve for the inputs of capital and labour? 0 K, : LI 0 Km : 3Lz O 1 K2 2 7L: The Production Possibility Frontier for an economy is given by y = 16-223/2 If the economy is producing 16 units of good x, then its MRT is equal to O2 0 4 O 8 12 O 16 Not enough information to determine
