Assignment Problem (ICWAI Final)

ye to dec 2009 ka question he.  is question mera 1hr kharab kiya aur meri aisi taisi kar di

the blank spaces denote that you cannot travel from city A to city A itself which is pretty obvious. Put ahypothetical figure there, which should be exceptionally high so that it never gets selected. Take it as a varialbe ( x ) such that x is more than any number. or take 100 or 200. And then attempt to solve the normal way. 

@ HEY BRO

I THINK U WILL SATISFY WITH THE SOLUTION

IF U HV ANY DOUDT IN THAT

U CAN REPLY ME

OK BYE

replace blank spaces by assigning highest cost infinity and solve the problem as usual in minimisation remember this rule

infinity +infinity=infinity

infinity-infinity=infinity

infinity*infinity=infinity

infinity/infinity=infinity

Dear Sunil

The optimal cost i arrived is as follows  please others also can tell whether this optimal solution is right

City A =4

CITY B=3

CITY C=5

CITY D=3

CITY E=5

TOTAL =20

Hello Sunil...the ans would be:

From City         To city          Cost

A                        B                    4

B                        D                   3

C                        E                   5

D                        A                   3

E                        C                   5

TOTAL                                    20

Can anyone pls help me by suggesting some book which would act as reference books for solution of  problems in Linear Programming, Assignment, Transporation etc. I am appearing in GR IV ICWAI Final Examination in June 2011 and I am finding Study Material to be insufficient in this respect.
