processed on three machines A, B and C. One unit of product I require 2 hours on
machine A, 1 on machine B and 6 on machine C, while one unit of product II requires
respectively 2 hours, 5 hours and 2 hours on machines A, B and C. In a given period,
there are 24 hours available on machine A, 44 on machine B and 60 on machine C.
The profit per unit on product I is Rs.6 and on product II is Rs.9. Given that the--- Content provided by FirstRanker.com ---
machines are available when required, Using graphical method, how many units of
each product should be made during the period in order to maximize the total profit? [10]
OR - Product A requires 4 and 2 man hours and product B requires 2
and 4 man hours at the machine centres I and II respectively per product. The profit--- Content provided by FirstRanker.com ---
per product of A is Rs.8 and product B is Rs.6. Using simplexl method, find the
optimum production for maximum profit. [10] - Three factories producing 100, 125 and 75 units of goods respectively supply five
distribution centers which demand 100, 60, 40, 75 and 25 units of the goods
respectively. The cost of transporting these goods is given by the following matrix C,--- Content provided by FirstRanker.com ---
where the element Cij represents the cost of transporting one unit of goods from the
ith factory to the jth distribution Centre.

Find the assignment which minimizes the total cost of the project. Each contractor has
to be assigned one job. [10]
OR - A salesmen has to visit five cities A,B,C,D and E. The distances (in hundred km)
--- Content provided by FirstRanker.com ---
between the five cities are given in the following table. If the salesmen starts from
city A and has to come back to city A, which route should he select so that the total
distance travelled by him is minimized? [10]

pay him 5% commission on each sale. He specifies certain conditions. The estate agent
must sell property A first, and this he must do within 60 days. If and when A is sold the
agent receives his 5% commission in that sale. He can then either back out at this stage
or nominate and try to sell one of the remaining two properties within 60 days. If he
does not succeed in selling the nominated property in that period, he is given the--- Content provided by FirstRanker.com ---
opportunity to sell the third property on the same conditions. The following table
summarises the prices, selling costs (incurred by the estate agent whenever a sale is
made) and the estate agent's estimated probability of making a sale.
Property A B C Price of Property 12,000 25,000 50,000 Selling costs 400 225 450 Probability of sale 0.7 0.6 0.5

Indicate the decision taken under the following approach a) pessimistic b) Optimistic
c) Regret and d) Equal Probability. [10] - In a reservation counter with a single server, customers arrive with the inter arrival
time as the exponential distribution with mean 10 minutes. The service time is also
assumed to be experimental with mean 8 minutes. Find (a) idle time of the server--- Content provided by FirstRanker.com ---
(b) the average length of the queue (c) the expected time that a customer spends in the
system. [10]
OR - Goods trains are coming in a yard at the rate of 30 trains per day. The inter-arrival
time follows exponential distribution. The service rate follows an exponential--- Content provided by FirstRanker.com ---
distribution with an average of 36 minutes. The yard can admit 9 trains at a time
(there being 10 lines, one of which is reserved for shunting purposes). What is the
probability that the yard is empty and find the average queue length? [10]
