consider an economy whre Y =C+I.
FOR values Y LESS THAN OR EQUAL TO 1500(Y<1500) , C= 200+0.6Y AND ANY AMOUNT OF AGGREGATE INCOME IN EXCESS OF 1500 UNITS CURRENCY IS ENTIRELY SAVED IN THE ECONOMY.IF THE FULL EMPLOYMENT LEVLE OF INCME IS 1750.
WHAT IS THE MINIMUM VALUE OF I NECESSARY TO ENSURE FULL EMPLOYENT IN THE ECONOMY ?
PLZ EXPLAINS THE STEP ALSO? PLZ

OK ...I proceeded this way...Y*=1750 but consumption only holds for y<=1500 therefore consumption, C at 1500= 200+0.6(1500)
C=1100
And for equilibrium of Y=1750 to hold ...1750=1100+I
I=650..

thankew vaibhav.

and if u have jnu sample papers.

can u plz tell me how do we solve ques 11-16 of year 2010.

vaibhav i hav a doubt.

at y greater than 1500 we are entirely saving that means we are not consuming nything,

so why at y=1750 u hav added consumption to find out investment

coz according the ques there is no consumption beyond 1500

... [show rest of quote]

[Dreyfus]

Dats y I used the max limit of y ie 1500 for consumption......and when income y is only consumed and invested dat means 1100 of consumption together with 650 of investments yields a full employment level of income of 1750!

11 - 16 work through options
Q11
Profit = TR-TC, TR = PQ TC = FC +VC
Profit at Q= 6, 20*6 - (93+15)= 12
work like this for the remaining options at Q = 7, profit is 13 which is highest. (b)
Q12
again solve profits at all Q=6,7,8,9 given P = 19
You will find same Profit at Q= 6and7
So Find MC = P =19 which is at Q =7 (b)
Q13
when P is 20 profit is 13 at the profit maximizing level of output.
when P is 19 profit is 6 at the profit maximizing level of output.
(c) is the answer

Now rest you can do yourself
Q14 Profit is -15 at Q = 0. Rest are more than -15. so (c) is the answer
Q15 Profit is -5 at Q = 5. so (d) is the answer.
Q16 Loss is the -5 solved in 15th question. So (a) is the answer
