query 1 : what are the answers of the questions from 88 to 92 jnu 2012 ?
query 2 :where do we have to do the gk from for jnu

[Akshay Jain]

sol for 88-92
it is given that the value of each cow's production is V(n)
for 1 cow it is 22 rs
for 2 cows it is 18+18=36 rs n so on
sol 88. for max profit MR=MC
at n=4 the profit max condition is satisfied (we have to take descrete units)
each cows production value is 12 and mc=11.
sol 89. we have to max the difference between TR and TC
for n=1 TR-TC= 22-11=11
for n=2 TR-TC=18+18-22=14
for n=3 TR-TC=15+15+15-33=12
chek for all values of n
so n=2
sol 90. in equilibrium 4 cows will be purchased
TR-TC=12*4-11*4=4
sol 91. cnt undrstand
sol 92. after tax total cost will be 21 per cow so only 1 cow will be purchased. tax revenue is rs 10

[kogo]

for ques 88 is v(n) the MR or TC(n)-TC(n-1)
if we go according to TC(n)-TC(n-1) formula then the equilibrium no. of cows brought is 2
this is as follows:-
   TR   TC
1  22   11
2  36   22
3  45   33
4  48   44
5  50   55
6  54   66
7  56   77
so the profit is maximised in buying 2 cows
please correct me if i am wrng
