Solution
Ans1) ans is D because when P=2.5 then quantity demanded=1000000 which is satisfied only by 4th option.
I.e. Put P=2.5 then demand=1000000
B) TR=PQ=P(1500000-200000P)=1500000P-200000P2
Total revenue is maximised when dTR/dP=0
Differentiating with P we get
1500000-400000P=0
P=15/4=3.75
Thus ans is A
