Emerson said that the poet was landlord, Sealord, airlord. The flight of imagination made the poet master of land, sea and air. But a poet's dream of yesterday becomes today an actual achievement and a reality for all men. Even those who invented, improved and perfected the aeroplane could hardly have dreamt of the possibility of flight into outer space.

Quantitative Aptitude [ Question No: 1 To 3 ] :
The digits of a two-digit number add up to 12, and the number formed by reversing them is 18 greater. The number is:
Your Answer : (Not Answered)
Correct Answer : A
Let the number be \( 10a + b \) with \( a + b = 12 \).
Reversing adds 18:
\[ (10b + a) - (10a + b) = 9(b - a) = 18 \quad\Longrightarrow\quad b - a = 2 \]
\[ a = 5, \quad b = 7 \quad\Longrightarrow\quad 57 \]
In a group of 80 people, 35 speak only Hindi and 20 speak only English. If everyone speaks at least one language, how many speak both?
Your Answer : (Not Answered)
Correct Answer : C
The total number of people is the sum of those who speak only Hindi, only English, and both.
Total = (Only Hindi) + (Only English) + (Both)
80 = 35 + 20 + (Both)
80 = 55 + (Both)
Both = 80 - 55 = 25.
In a 550 m race, the ratio of the speeds of two contestants P and Q is 3 : 4. P has a start of 170 m. Then, P wins by:
Your Answer : (Not Answered)
Correct Answer : B
To reach the winning post A will have to cover a distance of (550 - 170)m, i.e., 380 m.
While P covers 3 m, Q covers 4 m. (380 * (4/3)) = 506
While P covers 440 m, Q covers
Thus, when P reaches the winning post, Q covers 506 m and therefore remains 44 m behind.
P wins by 44 m.

Statement: It is not true that the mightiest superpower always wins wars and gets accolades from other countries.
Assumptions:
1. Winners are sometimes admired and appreciated.
2. Winners are occasionally criticized.
Your Answer : (Not Answered)
Correct Answer : E
The statement mentions that superpowers do win wars but their victory is not always applauded, but sometimes criticized as well in case the victory is an act of oppression of the weaker nation, and is not backed by a reasonable cause. So, both I and II are implicit.
Statement: Why don't you invite Anthony for the Christmas party this year?
Assumptions:
1. Anthony is not from the same city.
2. Unless invited Anthony will not attend the party.
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: Only assumption II is implicit
Proposing to invite Anthony takes for granted that he will not come unless he is asked - assumption II. Assumption I, that he lives elsewhere, is nowhere required by the suggestion. Only II is implicit.

In the given question, two words are given such that they have a relation to each other followed by four lettered pair of words. Select the lettered pair that has the same relationship as the original pair of words.
Triangle: Hexagon
Your Answer : (Not Answered)
Correct Answer : A
The matching pair is Square : Octagon.
A triangle has 3 sides and a hexagon 6, so the second figure has twice the number of sides of the first. A square has 4 sides and an octagon 8, the same relationship.
Triangle : Angle relates a figure to a part of it. Circle : Cuboid pairs a plane figure with a solid. Rectangle : Pentagon is 4 sides to 5, an increase of one rather than a doubling.
Statements:
I. No window is a glass.
II. Some glasses are doors.
Conclusions:
I. No window is a door.
II. Some doors are not windows.
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: If only conclusion II follows.
The glasses that are doors are, by the first statement, not windows - so some doors are not windows, conclusion II. Conclusion I excludes all doors from windows, which does not follow. Only II follows.

Each second number is two and a half times the first: \( 12 \times 2.5 = 30 \), so \[ 14 \times 2.5 = \mathbf{35} \]
Emerson said that the poet was landlord, Sealord, airlord. The flight of imagination made the poet master of land, sea and air. But a poet's dream of yesterday becomes today an actual achievement and a reality for all men. Even those who invented, improved and perfected the aeroplane could hardly have dreamt of the possibility of flight into outer space.
The passage best supports the statement that:
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: what man imagined has never been impossible; he has always turned it a reality through his conception of ideas and sheer hard labour.
The passage traces one line: the poet imagines mastery of land, sea and air; a poet’s dream of yesterday becomes today an actual achievement; and flight, once imagined, was built and then surpassed by flight into space.
So imagination is presented as the first step towards achievement, not as a test of poetic skill and not as a claim that every imagining comes true - the passage speaks of what has been realised, not of everything conceivable.

Plants growing in full sunlight are heliophytes, from the Greek helios, sun.
They have small thick leaves, a heavy cuticle and a high rate of photosynthesis at high light. Sciophytes are shade plants, with large thin leaves that saturate at low light.
Your Answer : (Not Answered)
Correct Answer : A
Buoyancy depends on the mass of the liquid displaced.
By Archimedes' principle the upthrust equals the weight of fluid displaced: \[F_B = \rho_{fluid}\,V_{displaced}\,g\] It does not depend on the mass of the body, nor on the depth once the body is fully submerged, nor on its shape except through the volume displaced.
Your Answer : (Not Answered)
Correct Answer : D
The earliest thermometer was developed by Galileo.
His thermoscope of about 1593 used the expansion and contraction of air in a bulb to move a column of water. It had no fixed scale, so it showed changes in temperature without measuring them; Fahrenheit's mercury thermometer with a scale came in 1714.
In which of the famous temple of Tamil Nadu, Shiva is worshipped as “Natraja”?
Your Answer : (Not Answered)
Correct Answer : C
It is at Chidambaram.
The Thillai Nataraja temple is where Shiva is worshipped as the cosmic dancer, and it is one of the five elemental temples, representing space or ether. The sanctum's Chidambara Rahasya is an empty space behind a curtain.

Correct Answer : B
Vanya Mishra won it.
She was crowned Femina Miss India World in 2012 and went on to represent India at the Miss World pageant that year.
Which of the following food grain crops occupies the largest part of the cropped area in India?
Your Answer : (Not Answered)
Correct Answer : C
Rice occupies the largest share of the cropped area.
It is grown on about 44 million hectares, chiefly in the eastern and southern states where rainfall exceeds 100 cm, followed by wheat at about 30 million hectares in the north-west. India is the second largest producer of both.
Electrical Drives [ Question No: 18 To 18 ] :
A drive for a lift door is required to
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: close gently and reverse on obstruction
A lift door must not injure anyone in its way, so it closes with limited force and reverses the moment an obstruction is sensed. Speed is secondary to that, and a door drive is specified for its sensitivity and its reversal behaviour rather than for its power.
Electrical Machines [ Question No: 19 To 19 ] :
At starting, the winding of a 230V, 50Hz, split-phase induction motor have the following parameters:
Main winding: R = 4 Ω ; XL = 7.5 Ω
Starting winding: R = 7.5 Ω ; XL = 4 Ω
The current in the main winding is _______.
Your Answer : (Not Answered)
Correct Answer : D
The current in the main winding is 27 A.
At starting the main winding is connected directly across the 230 V supply, so its current is the voltage divided by its impedance.
\[ \begin{aligned} Z_{m} &= \sqrt{4^{2} + 7.5^{2}} = \sqrt{72.25} \\ &= 8.5\ \Omega \\ I_{m} &= \frac{230}{8.5} = 27.06\ \text{A} \end{aligned} \]
The starting winding has the same impedance (8.5 Ω), so it also draws 27 A, but with a different phase angle; the line current is their phasor sum, which is less than twice that. 11.5 A, 22 A and 9 A do not follow from the winding impedance.
Electromagnetic Field Theory [ Question No: 20 To 20 ] :
The ratio of electric field intensity E and magnetic field intensity H has numerical value in free space :
Your Answer : (Not Answered)
Correct Answer : B
The ratio E/H in free space is about 377 Ω.
This ratio is the intrinsic impedance of free space:
\[ \begin{aligned} \eta_0 &= \sqrt{\frac{\mu_0}{\varepsilon_0}} \\ &= 120\pi \approx 377\ \Omega \end{aligned} \]
75 Ω is the characteristic impedance of common coaxial cable used for television, and 35 Ω and 225 Ω have no special meaning for plane waves in free space.
