so i think D.

[Var1995]

If the total revenue from sales of X is given by the equation R = 100Q -2Q^2. what is
the point elasticity of demand when MR = 20.

what will be the ans?

[Ansh malhotra]

I am not able to get your total revenue equation please post pic of the question

[Var1995]

  i have corrected the revenue function

[Akash]

Rev=Q*P
P=100-2Q (this is the demand)

also, MR=100-4Q=20
So, Q=4
and P= 60 (from demand)


elasticity =dQ/dP*P/Q

dQ/dP=-1/2 (of demand)

elasticity= -1/2*60/5=-6

Is this the answer?

[Var1995]

i solved this the same way n got -.25. but the options given in the ques r 1, 1.5, 2 and 2.5.

 Q is cmg out to be 40.

[Akash]

Q=20 for me. i calculated wrong

So elastiicty=-(1/2)*(60/20)

=-1.5

someone help me with this.

[Var1995]

56. British colonial economy prospered due to:
A. Extraction of Tributes from colonies
B. A new international division of labour
C. Industrial Revolution
D. All of the above

D?

[Ayushya Kaul]

I think it should be D.

[ranjankumarnayak5]

Exact way is ((10000/9600)^4)-1
But it gives 17.8%


Or if you just do simple interest, you can do 4*((10000/9600)-1)
Which gives 16.7%

I think ans is d
