    Andaman and Nicobar Islands consist of mainly two groups of islands, with distinctive features of the original residents — Negroid and Mongolese. It is strange to see how these two different groups migrated to these islands so far from the mainland — from India and Myanmar. The aboriginals found in these islands are the Jarawas, Sentineles, Onges, Shompenites, mainly found in Andaman and the Nicobarese in Nicobar. Of these, the Nicobarese in general, and some of the Onges, have accepted the so-called modern civilisation and learned the use of modern tools and facilities.

    They can be seen frequently in the Port-Blair market. The aboriginals are looked after by the Anthropological Department of the Government, who make regular visits to their islands and supply them with food and other necessities.

    These aboriginals still do not know how to use a matchbox and prepare fire by rubbing two pieces of wood; they also do not know the use of cloth. If the people from the Anthropological Department offer them clothes, they use them only as turbans and not to wrap their bodies.

  • Question 27
    1 / -0

    Choose the correct option which changes the underlined phrase into a clause.

    I felt sick after seeing the horror movie.

    Solution

    A clause has a subject and a verb. So, a subject is required to convert the phrase into a clause. So, the subject 'I' will be added. Moreover, the use of 'felt' indicates past tense. So, the verb will be in past tense. Hence, use of 'saw' is correct. Hence, option 4 is the correct answer. Other options make the sentence ungrammatical.

     

  • Question 28
    1 / -0

    Find the option which correctly changes the voice of the sentence given below.

    The neighbours took the injured people to the hospital.

    The injured people ______ to the hospital by the neighbours.

    Solution

    The sentence is in simple past. So, in passive voice the structure will be 'was + past participle form of verb'. Since, 'people' is plural the plural verb 'were' will be used. The past participle form of 'took' is 'taken'. 

     

  • Question 29
    1 / -0

    In the following question, a sentence has been given in direct speech. Out of the four alternatives, select the one which best expresses the same sentence in indirect speech.

    Sentence:

    I said to them, ''Do not walk barefoot on the grass.''

    Solution

    The context sentence is an imperative sentence. In such sentences, we use 'advised' in place of the reporting verb when an advice is being given and 'not to' in place of 'do not'. Inverted commas are deleted. No change in tense takes place.
    Option (3) has all the modifications in the sentence as per the rules of direct/indirect speech. Thus, it is the correct answer. Option 2 is incorrect as there is an error of split infinitive (to not walk).

     

  • Question 30
    1 / -0

    The sentence below has a word in capital letters. Select the synonym of the word as per the context.

    You need not ABANDON hope till the result is declared.

    Solution

    (1) 'Abdicate' is not appropriate because it means 'to give up a position of power'.
    (2) 'Desert' is not appropriate because it is used for leaving someone without help or in a difficult position.
    (3) 'Give up' is appropriate because 'abandon' means 'give up completely (a practice or a course of action).'
    (4) 'Surrender' is not appropriate because it means 'to stop fighting or to accept defeat'.

    1 / -0

    In the sum 3a + 4a + 5a + 6a + 7a, which term can be removed so that the resulting sum is divisible by 4 for every positive integer a?

    Solution

    The given sum is 25a. The numbers less than 25a which will always be divisible by 4 are 4a, 8a, 12a, 16a, 20a and 24a. Of these, 20a can be obtained by subtracting 5a from the given sum.

     

  • Question 32
    1 / -0

    By which smallest number must 90 be multiplied to make it a perfect square?

    Solution

    Factors of 90 are = 3 × 3 × 5 × 2
    Since '10' is not in pair, we multiply 90 by 10 (2 × 5) to make it a perfect square.

     

  • Question 33
    1 / -0

    What is the smallest number by which 3087 must be divided so that the quotient obtained is a perfect cube?

    Solution

    3087 = 7 × 7 × 7 × 9
    To obtain a perfect cube, we need to divide 3087 by 9.

     

  • Question 34
    1 / -0

    A positive number is 5 times the other number. If 21 is added to both the numbers, then greater of the two numbers becomes twice the smaller number. What are the numbers?

    Solution

    Let one number be x.
    Other number = 5x
    Adding 21 to both numbers, they become x + 21 and 5x + 21, respectively.
    According to the question, we have
    5x + 21 = 2(x + 21) (As 5x + 21 is greater)
    5x + 21 = 2x + 42
    ⇒ 5x - 2x = 42 - 21
    ⇒ 3x = 21
    ⇒ x = 21/3 = 7
    Numbers are 7 and 35.

     

  • Question 35
    1 / -0

    The lengths of two sides of a triangle are 7 units and 9 units. Which of the following can be the measure of the third side?

    Solution

    Length of the third side lies between (9 - 7) units and (9 + 7) units, or 2 units and 16 units.
    Or, 2 units < Length of third side < 16 units
    Hence, the length of the third side can be 13 units.

     

  • Question 36

    Which of the following options shows the factorised form of (5a2 - 21a + 18)?

    Solution

    (5a2 - 21a + 18)
    = 5a2 - 15a - 6a + 18
    = 5a(a - 3) - 6(a - 3)
    = (5a - 6)(a - 3)

     

  • Question 37

    In a trapezium, the shortest distance between the two parallel sides is 30 m and its area is 900 sq. m. If the ratio between the lengths of the parallel sides of the trapezium is 3 : 2, then find the sum of the lengths of the parallel sides.

    Solution

    Given: Area of the trapezium = 900 m2
    Height = 30 m
    We know,
    Area of trapezium = 1/2 (sum of parallel sides) × height

    Let the sum of parallel sides be 'x'.

  • Question 39
    1 / -0

    If a + b = 7 and ab = 12, find the value of a2 + b2.

    Solution

    (a + b) = 7
    Squaring both sides, we get:
    a2 + b2 + 2ab = 49
    Putting in the value of 'ab' as 12, we get
    a2 + b2 + 2(12) = 49
    a2 + b2 = 49 - 24 = 25

     

  • Question 40
    1 / -0

    If a + b + c = 9 and ab + bc + ca = 26, then find the value of a2 + b2 + c2.

    Solution

    (a + b + c)2 = a2 + b2 + c2 + 2 (ab + bc + ca)
    81 – 52 = a2 + b2 + c2
    a2 + b2 + c2 = 29

     

  • Question 41
    1 / -0

    The perimeter of a rectangle and a square is 320 cm each. The difference between their areas is 800 cm2. If the area of rectangle is less than that of square, then find the area of rectangle.

    Solution

    Perimeter of rectangle = Perimeter of square = 320 cm

    Let 'a' be the side of the square.
    4a = 320 cm
    a = 80 cm
    Area of square = 6,400 cm2

    Let the length and breadth of the rectangle be 'l' cm and 'b' cm respectively.
    So, 6400 - Ib = 800
    Ib = 5,600 cm2

     

  • Question 42
    1 / -0

    The distance travelled by a car is directly proportional to the time. The car travelled a distance of 180 km in 2 hours. How long will it take to travel a distance of 900 km?

    Solution

    Distance α Time

    d = kt

    180 = k x 2

    k = 180/2 = 90

    Now, 900 = kt

    900 = 90 x t

    t = 10 hr

  • Question 50
    1 / -0

    Which of the following statements is not applicable to carbon compounds?

    Solution

    Carbon compounds are formed by covalent bonds. They have weak inter-molecular forces of attraction. So, they are non-polar in nature and are known as covalent compounds.
    Hence, the statement in option (2) is incorrect.
    All the other statements regarding carbon compounds are correct.
    Due to weak forces of attraction between covalently bonded carbon compounds, they have low melting and boiling points.
    Carbon compounds form homologous series which are groups of compounds with the same general formula and similar properties.
    Due to non-polar nature of carbon compounds, they are generally soluble in organic solvents.
