Till now, every student of the class has appeared in 100 school level tests. The students had following distribution of marks in the tests, in terms of “average” and “number of times a student scored 100% marks”.

    Ms. Oberoi has carefully studied chances of her school winning each of the Olympiads. Based on in-depth calculations, she realized that her school is quite likely to win district level Olympiad but has low chances of winning the international Olympiad. She listed down the following probabilities of wins for different Olympiads. Prize was highest for international Olympiad and lowest for district level Olympiad (in that order).

    All the students are studying in the school for last ten years. She wanted to select the best team for all four Olympiads (Ms. Oberoi had no other information to select students).

    Direction (8-10): Read the following case-let and choose the best alternative for the questions that follow:

    Hewlett Packard (HP) was doing a roaring business. Demand of the products was high and supply of raw — material was abundant. HP was manufacturing three different products, some customers bought two types of products and some bought only one. The three products were “quickie-quick”, ‘run-of-the-mill”, and “maxi-max”. Customers were not complaining loudly.
    Kabir, the product manager, was confused! Demand for “quickie-quick” was increasing. Raw material suppliers wanted to supply lower quality at cheaper price. It was profitable for the company to increase production. Quality department was not happy with the product. Kabir met Shiva, the CEO, who, as always, wanted higher profits. He said that HP will set tip a committee for improving the quality.

    8. What must not be done by Kabir?

    a) Only produce “quickie-quick” as it gives highest profits.

    b) Increase the production for “quickie-quick” and ask the supplier for better quality raw material.

    c) Maintain the level of production for “quickie-quick” and ask the supplier for better quality raw material.

    d) Reduce the production of “quickie-quick” till committee submits its report.

    e) Stop production of “quickie-quick” till committee submits its report.

    9. Shiva set up a “brand” committee comprising of a few selected managers, headed by Robert. The committee proposed that HP should continue to manufacture the three differently branded products. It also proposed to recruit a new brand manager for improving brand image of the products. It agreed with Shiva that the company should increase the price. Atom Singh, head of sales, was confused because he realized that customers were miffed with ‘run — of — the — mill” and “maxi — max”.
    What should Atom Singh do?

    a) Launch one more product to increase sales.

    b) Stop production of quickie — quick.

    c) Launch a campaign on social media to increase awareness about company’s products.

    d) Send an anonymous email to all the employees highlighting customer dissatisfaction.

    e) Conduct a research study to find out the reason for customer’s dissatisfaction.

    10. Some of the managers in production department were discussing the problems faced in shipping products in time. They complained that they had to undertake responsibility of creating financial and marketing plans in addition to responsibility of production planning. At the same time, finance and marketing managers were to be involved in preparing production plans. It was expected that this will reduce customer complaints. It was rumored that these changes were initiated by the managers educated in the U.S.
    Which of the following is the best possible course of action available to the affected managers?

    a) Create a union to safeguard their rights.

    b) File a law suit against the company.

    c) Create a forum for discussion and resolution of issues.

    d) Register a complaint with the human rights body.

    Explanation for (1 - 4):

    Explanation: 5) The probability of winning in the international Olympiad is very less (5%). So the students selected for it should have a greater chance of scoring 100%.
    Option (1) is eliminated because 4 & 11 score 100% just once.
    In option (2), the combined number of times 100% is scored is
    15 + 12 + 20 = 47
    In option (3), the combined number of times 100% is scored is
    7 + 10 + 6 = 23
    In option (4), 2 of the members score 100% less number of times. Combined 100% is 2+20+5=27
    In option (5), the combined number of times 100% is scored is
    7 + 8 + 1 = 16

    Explanation: 6) The probability of winning in the district level Olympiad is high (95%). So Ms. Oberoi needs to select students who have high averages. The number of times the students score 100% is not important. Students 4 & 11 have high an average of 70 and they score 100% just once. So option (1) is eliminated as it has No. 14 student who has scored 100% 20 times. Similarly, option (3) is also eliminated. In options (2) and (4), we select option (4) as the correct option because both students 1 & 13 have the same average but student 13 scores 100% just twice..

    Explanation: 7) A student selected for international Olympiad cannot be selected for national Olympiad. So, students 2, 8 and 14 cannot be a part of national team. The probability of winning in the national Olympiad is 10%. So, here the stress should be on the number of times 100% is scored. Also, the students with higher averages are preferred.
    Option (1) has students having high averages but lesser 100% scores.
    Option (2) has students having lower average scores like 60.
    Option (3) has all the students having an average score of 60.
    Option (4) has students having higher averages of 65 and 70. Also, their combined 100% scores is very high, 8 + 10 + 7 = 25.

    Explanation: 8) In order to arrive at the correct answer for this question, one must read it very carefully.
    The passage mentions that, “some customers bought two types of products and some bought only one”. This implies that “run-of-the-mill” and “maxi-max” were in demand as well. Thus, Kabir must not only produce the “quickie-quick”.
    All of the other options indicate courses of action that Kabir must undertake.

    Explanation: 9) The affected managers in this scenario are those in the production, finance and marketing departments.
    From the information given in the caselet, one may infer that their rights were certainly not violated in any manner. This eliminates options 1, 2 and 4.
    Option 5 is not only farfetched but also erroneous. Going to the U.S. for further education is completely uncalled for.
    Creating a forum for discussion will bring everyone’s ideas to the table and facilitate resolution of the mentioned issues.

    Explanation: 10)  Atom Singh realized that customers were upset with “run-of—the-mill” and “maxi-max. Hence, the decision he takes must take this into consideration.
    “Launching one more product’ is uncalled for at this stage. Eliminate option 1.
    The customers have not been mentioned as being upset with “quickie-quick”. Eliminate option 2.
    Launching a campaign on social media to increase awareness does not address the customers’ mindset. Eliminate option 3.
    Option 4 is unprofessional in nature.
    Option 5 will bring the required insight to the scenario.
