14. A monopoly faces the demand curve P=8-Q. the monopoly has a constant unit cost equal to 5 for Q<=2 and a constant unit cost equal to 3 for Q<=2. its profit maximizing output equals:
(a) 3/2
(b) 2
(c) 5/2
(d) both 3/2 and 5/2
....the MR=MC condition gives values 3/2 and 5/2 .. which is the answer in key...
but wont we further find the profits both at 3/2 and at 5/2 ..
profit when Q=5/2:
PQ-3Q:
(8-5/2)*(5/2)-3(5/2)
=5/2*(8-5/2-3)
=5/2*5/2
=25/4
similarly for 3/2 it comes out to be 9/4..
since profit at 5/2> profit at 3/2
so 5/2 is the answer.?
que. Integrate
e to d power minus x^2/2 dx
lower limit 1.96
upper limit infinity .
I'm not getting the exact ans,please someone upload their working :\
