Hi Devika.. :)

Suppose, U1= 2(x1)+y1 and U2 = x2+y2.

Then, set of pareto optimal allocations will be x axis of Agent1 nd y-axis of Agent2.

Suppose, U1=x1+y1 and U2 =2(x2)+y2

Then, set of preto optiomal allocations will be x-axis of Agent2 and y-axis of Agent1.

Dont' try to memorise according to which MRS is greater.

Always try to plot the edgeworth and check.
