  1. A small scale industry manufactures two products I and II. These products are

    --- Content provided by FirstRanker.com ---

    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
  2. 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]
  3. 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.
    3 2 4 1 1

    Determine the number of units of goods to be transported from each of the three
    factories to the various distribution centres so that the total transportation cost will be

    --- Content provided by FirstRanker.com ---

    a minimum. [10]
    OR
  4. A project work consists of four major jobs for which four contractors have submitted
    tenders. The tender amounts quoted in the thousands of rupees are given in the matrix

    C3 17 25 37 15
    C4 14 31 39 21

    Find the assignment which minimizes the total cost of the project. Each contractor has
    to be assigned one job. [10]
    OR
  5. 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]
    To
    A B C D E
    From A 4 7 3 4

    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

    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 ---

  9. 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
