    11. Read the following passage and answer the questions (11 to 15) accordingly.

    What is intelligence , anyway ? When I was in the Army I received a kind of aptitude test that all soldiers took and, against a normal of 100 , scored 160. No one at the base had ever seen a figure like that and for two hours they made big fuss over me. (It didn't mean anything. The next day I was still a buck private with KP as my highest duty.)

    All my life I've been registering scores like that , so that I have the complacent felling that I'm highly intelligent, and I expect other people to think so, too.Actually, though ,don't such scores simply mean that I am very good at answering the type of academic questions that are considered worthy of answers by the people who make up the intelligence tests-people with intellectual bents similar to mine?

    I had an auto repairman once, who on these intelligence tests, could not possibly have scored more than 80 , by my estimate.I always took it for granted that I was far more intelligent than he was. Yet, when anything went wrong with my car I hastened to him with it, watched him anxiously as he explored its vitals, and listened to his pronouncements as though they were divine oracles and he always fixed my car.

    He had a habit of telling me jokes whenever he saw me. once time he raised his head from automobile hood to say : " Doc, a deaf-and-dumb guy went into a hardware store to ask for some nails. He put two fingers together on the counter and made hammering motions with the other hand. The clerk brought him hammer.He shook his head and pointed to the two fingers he was hammering. The clerk brought him nails. He picked our the sizes he wanted and left. Well doc, the next guy who came in was blind man. He wanted scissors. How do you suppose he asked for them? "

    Indulgently, I lifted my right hand and made scissoring motions with my first two fingers. Whereupon the auto repairman laughed raucously and said , " Why, you dumb jerk, he used his voice and asked for them." Then he said smugly , "I've been trying that on all my customers today." " Did you catch many?" I asked. "Quite a few." He said. "But I knew for sure I'd catch you." "Why is that?" I asked. "Because you are so ... educated ,doc, I knew you couldn't be very smart."

    And I have an uneasy feeling he had something there.

    The Central idea of the passage is :


    Answers

    You are not expected to be too intelligent if you want to serve in the Army.

    Answers

    None of above

    Answers

    that the author is dumb.
    that the author is not as smart as he think he is.

    Suppose we take only one Muslim.
    No. of selections of Muslims = 3C[SUB]1[/SUB] = 3
    No. of selections of Hindus = 8C[SUB]3[/SUB] = 56

    When we select 2 Muslims and 2 Hindus,
    number of ways of selecting Muslims = 3C[SUB]2[/SUB] = 3
    number of ways of selecting Hindus = 8C[SUB]2 [/SUB]= 28
    No. of parties = 28 X 3 = 84

    When we take 3 Muslims and 1 Hindu,
    number of ways of selecting Muslims = 3C[SUB]3[/SUB] = 1
    number of ways of selecting Hindus = 8C[SUB]1 [/SUB]= 8
    No. of parties = 8

    Total no. of parties = 168+ 84 + 8 = 260

    Total no, of ways of having at least 1 Muslim = Total no. of ways - all are Hindus = 11C[SUB]4[/SUB] - 8C[SUB]4[/SUB]
    = 260
