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

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

I felt sick after seeing the horror movie.

A
being seen the horror

B
having seen the horror

C
seen by me the horror

D
I saw the horror

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

Directions: 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.

A
were taken

B
were taking

C
were being taken

D
had been taken

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'. So, option 1 is the correct answer.
Question 29
1 / -0

Directions: 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.''

A
I requested them not to walk barefoot on the grass.

B
I ordered them to not walk barefoot on the grass.

C
I advised them not to walk barefoot on the grass.

D
I pleaded with them not to 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

Directions: 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.

A
Abdicate

B
Desert

C
Give up

D
Surrender

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'.
Question 31

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.

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?

A
5 and 25

B
7 and 35

C
6 and 30

D
8 and 40

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 = = 7
Numbers are 7 and 35.

A
102°

B
120°

C
125°

D
136°

Solution

In the given quadrilateral:
A = 2ABD
Now, A + 105° + 75° + ABD = 360°
2ABD + 180° + ABD = 360°
2ABD + ABD = 360° - 180°
3ABD = 180°
ABD = = 60°
Now, ABD + y = 180° (Supplementary angles)
60° + y = 180°y = 180° - 60° = 120°

ACB = 65°
BAC = 90° (Angle in a semicircle is a right angle)
In ABC, by angle sum property,
ABC + BCA + CAB = 180°
ABC + 65° + 90° = 180°ABC = 180° - 155° = 25°

A
19 units

B
17 units

C
13 units

D
2 units

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.

= 5a(a - 3) - 6(a - 3)
= (5a - 6)(a - 3)
Question 44

A
25°

B
28°

C
30°

D
32°

Solution

In the given figure,
∠FGD = ∠EFG = 105° (Alternate interior angles)
∠AEO + ∠FEO = 180° (Linear pair)
130° + ∠FEO = 180°
∠FEO = 180° - 130° = 50°
In FOE,
∠FEO + ∠EFO + ∠EOF = 180° (Angle sum property of triangles)
50° + ∠EOF + 105° = 180° (∵ ∠EFO = ∠EFG)
∠EOF = 180° - 155° = 25°

If ABCD is a square and BCE is an equilateral triangle, then what is the measure of DEC?

A
30°

B
45°

C
15°

D
60°

Solution

BCE is an equilateral triangle.
CE = BC = BE
ABCD is a square.
BC = CD
Hence, CD = CE
So, in CDE, we have
CD = CE
Hence, EDC = CED
Now, BCE = 60° [Since equilateral triangle and BCD = 90° (since square)]
Hence, DCE = DCB + BCE = (60° + 90°) = 150°
So, in DCE, EDC + CED = 30° (Since three angles of a triangle add up to 180°)
Hence, we have
DEC = EDC = 15° (Since DC = CE and therefore, angles opposite to equal sides are equal)

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.

A
5,600 cm²

B
6,400 cm²

C
3,200 cm²

In the figure, if || m, p || q, DAC = 30° and ABC = 70°, then what is the measure of ACD?

A
70°

B
80°

C
110°

D
150°

Solution

According to the data given in the question, || m and AC is a transversal.
∴ DAC = ACB [Alternate interior angles]
ACB = 30°
Also, q is a transversal.
∴ ABC + BCD = 180° [Co-interior angles]
70° + BCD = 180°
BCD = 110°
Now, ACB + ACD = BCD
30° + ACD = 110°
ACD = 110° - 30° = 80°
Hence, 80° is the correct answer.

A
must be negative

B
must be positive

C
must be zero

The resultant of all forces acting on a body is zero. Which of the following statements cannot be true?

A
The body is undergoing acceleration.

B
The body is at rest.

C
The body is rotating about its centre of mass.

D
The body is moving with a uniform velocity.

Question 84
1 / -0

If bodies A and B having masses 200 kg and 300 kg respectively are at rest, then the force required to change the state of rest will be

A
greater for body A

B
greater for body B

C
same for both the bodies

D
Cannot be determined

Solution

m_A = 200 kg
m_B = 300 kg
More the mass, more is the inertia of rest i.e. more will be the force required to change the state of rest.
Hence, B will require larger force.
