11. Consider the following statements and choose the right option
A. Middle term should be distributed in atleast one premise
B. Middle term should be present in the conclusion
C. Both premises can be particular in a valid argument
D. Both premises can be negative in a valid argument

  • Option : C
  • Explanation :
    'Middle term should be distributed in at least one premise' is the only correct statement among those given.
    Categorical syllogisms have exactly three categorical propositions, two of which are premises; and the third is the conclusion. There are exactly three terms, each appearing only twice.
    Four rules apply to all valid categorical syllogism:
    Rule 1: The middle term must be distributed in at least one premise.
    Rule 2: Any term that is distributed in the conclusion must be distributed in the premises.
    Rule 3: The number of negative premises must be equal to the number of negative conclusions.
    Rule 4: No particular conclusion can be drawn from exclusively universal premises. Arguments that pass each of these tests are valid. Those that fail to satisfy even one of the rules are invalid

12. When a large number of students with different performances levels are there in the class. For uniform imparting of educative interactions, a teacher should opt for a communication which is:

  • Option : B
  • Explanation :
    Technology enabled communication is most suited for uniform imparting of educative interactions. All such, it travels uniformly from the source and reaches every member of the audience regardless of their individual differences.
    Top down and linear communication style is suitable in organisations with multiple levels in hierarchy. Classroom teaching has ouly two levels-the teacher and the taught. Hierarchy in terms of performance levels is non-inclusive and undesirable in a class.
    Individual centric communication may challenge the teacher to ensure that every student in the class has received the information imparted, particularly when the class size is large. Individual differences among students would mean that some lag behind and fail to receive the communication.
    likewise, communication sel-projected by the teacher might fail to reach some students particularly when the class is large.

13. In case the population of research is heterogeneous in nature which of the following sampling techniques will ensure optimum representativeness of sample units?

  • Option : B
  • Explanation :
    Stratified random sampling works best in case of a heterogeneous population. It is a method of sampling that involves the division of a population into smaller sub-groups known as strata, on the basis of the members' shared attributes or characteristics such as income or educational attainment.

    Simple random sampling is suitable to a homogenous population. It involves separate random selection of each household.

    Cluster sampling is simple random sample is taken from each of the different clusters in the population. Multiple clusters of people are created from a population where they are indicative of homogeneous characteristics and have an equal chance of being a part of the sample.

    Systematic random sampling does not involve separate random selection of each household. It is often used to select large samples from a long list of households and therefore, proceeds in a systematic manner, selecting every nth member of population to be included in the study.

Reasons (R): Positive educative actions should guide learners to acquire knowledge of social significance.
In the light of the above two statements, choose the correct option:

The education policy is aims at educating its learner-citizens in keeping with the social demands of the nation. Institutions vary in the quality and level of resources, they make available for the teaching-learning process; so, institutional demands also influence and pre-decide classroom communication.
    The reason for this is that educative actions must be positively oriented and must also aim at positive outcomes so that learners acquire knowledge that is significant to fu1fil social demands. Hence, (R) is the correct reason for (A).

15. A person buys 3 items of Rs. 1500 each and 2 items of Rs. 1800 each from a shopping mall. On the total bill a discount of 10% is given. What is the average cost of the items?

  • Option : B
  • Explanation :
    Total cost of 3 items at the rate of ₹1500 each
    = 3 x 1500 = ₹4500
    Total cost of 2 items at the rate of ₹1800 each
    = 2 x 1800 = ₹3600
    Total cost of 5 items = 4500 + 3600 = ₹8100
    Discount = 10%
    Net cost = 8100 x (100-10)/100 = ₹7290
    Average cost of the item = 7290/5 = ₹1458
