RRB Section Controller/RRB Traffic Apprentice (RRB NTPC) Tier I Official Paper (Held On: 02 Apr, 2016 Shift 2) (Previous Year Paper)

Here the correct answer is QSPR.

Key Points:-

• The sentence 'Q' is independent of any other sentences as it is giving general information about the climate of India. Hence, 'Q' is the first part.
• Comprises refers back to the climate of India mentioned in the sentence 'Q'. Hence, 'S' follows 'Q'.
• It will be followed by P as wide range has been used for the weather conditions in India.
• 'Geographic' is an adjective which will be followed by a noun i.e. scale. Therefore, the sentence 'R' is the concluding sentence. 
  

Paragraph after rearranging the sentences: The climate of India comprises a wide range of weather conditions across a vast geographic scale and varied topography.

Hint

• Important Rules to Solve the Para Jumbles:
• Read the sentences attentively and try to comprehend the idea or theme of the sentence and eliminate the irrelevant options.
• Try to identify the opening (independent sentence) and closing sentences (concluding sentence).
• Try to identify the mandatory pairs. Two sentences can be connected through various connectors and other determinants.

Let, the numbers are 2x, 3x, and 5x

According to the problem,

⇒ 2 × (2x + 3x + 5x) = 100

⇒ 2 × (10x) = 100

⇒ 20x = 100

⇒ x = 5

∴ The largest number is = 5x = 5 × 5 = 25

∴ Square of the largest number = (25)² = 625

The correct answer is Womesh Chandra Bonnerjee.

• Womesh Chandra Bonnerjee was an Indian barrister and was the first president of Indian National Congress.
• He was the first Indian to contest the election for the British House of Commons although he lost the election

Principal(P) = 48000

Time(n) = 2 years

Rate of interest(r) = 20% p.a

∴ Amount = P(1 + r/100)ⁿ = 48000(1 + 20/100)² = 48000(1 + 20/100)² = 48000 × 1.44 = 69120

∴ Compound interest = (69120 - 48000) = Rs. 21,120

In the figure, AC = 20 m and ∠ACB = 30°

According to the question,

Let, length of the piece of cloth = x m

Cost of cloth = Rs. 35

∴ Cost of 1 m cloth = Rs. 35/x

According to the question,

⇒ (x + 4) (35/x - 1) = 35

⇒ 35 - x + 140/x - 4 = 35

⇒ 35x - x² + 140 - 4x = 35x

⇒ x² + 4x - 140 = 0

⇒ x² + 14x - 10x - 140 = 0

⇒ x(x + 14) - 10(x + 14) = 0

⇒ (x + 14) (x - 10) = 0

⇒ x = - 14 or 10

∴ The piece of cloth is 10 m long

Alternate Method

We can tabulate the given data according to the following table:

As the total remains constant at Rs.35, we get:

xy = 35     

⇒ x = 35/y      ----(i)

Also, (x – 1) × (y + 4) = 35      ----(ii)

On substituting the value of x from equation (i) into equation (ii), we get:

[(35/y) – 1] × (y + 4) = 35 

On solving, we get:

y = -14 and 10

∴ The piece of cloth is 10 m long

In the figure, BD = OC = 12 m and CD = OB = 15 m and AB = 20 m

∴ AO = AB - OB = 20 - 15 = 5 m

In ΔAOC we get,

⇒ AC² = AO² + OC²

⇒ AC² = 5² + 12² = 25 + 144 = 169

⇒ AC = 13

∴ Distance between their tops = 13 m

Let, the principal = Rs. 100x and rate of interest = r%

Simple interest for 2 years = Rs. 1200

∴ Simple interest for 1 year = Rs. 1200/2 = Rs. 600

∴ Compound interest for 1^st year = Rs. 600

∴ Compound interest for 2^nd year = Rs. (1290 - 600) = Rs. 690

∴ Difference between compound and simple interest for 2^nd year = Rs. (690 - 600) = Rs. 90

According to the question,

⇒ 600 × 1 × r/100 = 90

⇒ 6r = 90

⇒ r = 15

∴ Rate of interest = 15%

According to the question,

⇒ 100x × 2 × 15/100 = 1200

⇒ 30x = 1200

⇒ x = 40

∴ The principal = Rs. (100 × 40) = Rs. 4000

This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion. A sound wave traveling through air is a classic example of a longitudinal wave.

A wave in which the particles vibrate in the same direction of propagation of the wave is called a longitudinal wave.

Longitudinal waves can be produced in all three media such as solids, liquids, and gases. The waves which are produced in the air are always longitudinal.

In the statement it is mentioned that in some tier 2 cities, transportation isone of the major concerns but was never mentioned that all the tier 2 cities are not well connected. So, conclusion I is invalid.

CONCEPT:

• Electromagnetic waves: The wave which is generated due to vibration between electric field and magnetic field and it does not need any medium to travel is called an electromagnetic wave. It can travel through a vacuum.
• Light is a form of energy which is an example of an electromagnetic wave.
• Wavelength: The distance between two successive crests or troughs is called wavelength of the wave.
• Frequency: The number of vibration per unit time is called frequency.

Speed of wave (v) = frequency (f) × wavelength (λ)

• White light consists of seven constituent colours: Violet (V), Indigo (I), Blue (B), Green (G), Yellow (Y), Orange (O), Red (R).
• The frequency of the color light in the order from highest to lowest is given as acronym VIBGYOR (V > I > B > G > Y > O > R).

EXPLANATION:

• From the above discussion, the violet has the highest frequency and the shortest wavelength of the visible colors of light.
• The red color light has the lowest frequency and the longest wavelength of the visible colors of light. So option 3 is correct.

Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Pure tungsten has some amazing properties including the highest melting point (3695 K), lowest vapor pressure, and greatest tensile strength out of all the metals. Because of these properties it is the most commonly used material for light bulb filaments.

In mid - 2001, he spent nearly eight days in orbit as a crew member of ISS EP - 1, a visiting mission to the International Space Station.

C.P of the article = Rs. 1600

Profit = 10%

S.P of the article = Rs. 1600 + (1600 × 10/100) = Rs. (1600 + 160) = Rs. 1760

If S.P = Rs. 1840, ∴ Profit = (1840 - 1600) = 240

∴ Profit percentage = (240/1600) × 100 = 15%

∴ Increase profit percentage = (15 - 10) % = 5%

The Correct Answer is Option B i.e Cro - Magnon.

• Cro-Magnon was among the first fossils to be recognized as belonging to our own species—Homo sapiens.
• Cro-Magnon was discovered in 1868.
• This famous fossil skull is from one of several modern human skeletons found at the famous rock shelter site at Cro-Magnon, near the village of Les Eyzies, France.
• Homo Ergaster is an extinct species or subspecies of archaic humans who lived in Africa in the Early Pleistocene.

Given, 27_3_19_10 = 90

Now see the options and place the symbols,

27 x 3 - 19 ÷ 10 = (27 x 3) – (19 ÷ 10) = 81 – 1.9 → 79.1 ≠ 90

27 + 3 ÷ 19 - 10 = 27 + (3 ÷ 19) – 10 = 27 + (0.15) – 10 → 17.15 ≠ 90

27 + 3 - 19 ÷ 10 = (27 + 3) – (19 ÷ 10) = 30 – 1.9 → 28.1 ≠ 90

27 x 3 + 19 - 10 = (27 x 3) + (19 - 10) = 81 + 9 → 90 = 90

Thus option ( ×, +, - ) is correct one.

Calculation:

⇒ (2/7 + 3/5) ÷ (2/5 + 2/7) = (10 + 21)/35 + (14 + 10)/35

⇒ (31/35) ÷ (24/35)

⇒ 31/24

Given, 44_4_7_5 = 82

Now see the options,

44 x 4 - 7 ÷ 5 = (44 x 4) – (7 ÷ 5) = 176 – 1.4 = 174.6 ≠ 82

44 + 4 ÷ 7 - 5 = 44 + (4 ÷ 7) - 5 = 44 + (0.57) – 5 = 39.5 ≠ 82

44 + 4 - 7 ÷ 5 = 44 + 4 – (1.4) = 48 – 1.4 = 46.6 ≠82

44 ÷ 4 x 7 + 5 = ((44 ÷ 4) x 7) + 5 = ((11) x 7) + 5 = 82

Hence option ( ÷, ×, + ) is correct one.

Sum of the digit in odd places = 9 + 0 = 9

Sum of the digit in even places = R + 1

∴ The difference of sum of odd place digit and sum of even place digit = (9 - R - 1) = 8 - R

For a number to be divisible by 11 the difference has to be 0 or a multiple of 11

In this case, we get

⇒ 8 - R = 0

⇒ R = 8

Consider Malini as yourself

Maternal aunt’s mother → grandmother

Grandmother’s only son → maternal uncle

Uncle’s son → cousin

So, Malini is the cousin of Rohit.

A hardcourt (or hard court) is a surface or floor on which a sport is played, most usually in reference totennis courts.

Given, 36 – 4 + 7 x 8

Now replace the symbols

36 – 4 + 7 x 8 → 36 + (4 x 7) - 8 = 56

Hence, 56 is the correct answer.

First multiple of 12 = 12 × 1 = 12

20^th multiple of 12 = 12 × 20 = 240

∴ required average = (12 + 240)/2 = 252/2 = 126

The average of the first 20 multiples of 12 = (First multiple of 12 + 20th multiple of 12)/2

Ascending order of the given list = 31, 53, 55, 56, 59, 61, 69

Number of data in the list = 7

∴ Median = (7 + 1)/2 = 4^th number of the list = 56

Given:

Sum of digits of two-digit number = 9

When digit are reversed then the number decreased by 45

Calculation:

Let the two-digit number be 10x + y

So, the reversed number is 10y + x

Now, According to the question

x + y = 9       ----(1) 

10x + y = 45 + 10y + x

⇒ 9x - 9y = 45

⇒ x - y = 5      ----(2) 

From (1) and (2), we get 

x = 7 and y = 2

∴ The two digit number is 10 × 7 + 2 = 72

The logic followed is:

Similarly,

Hence, the correct answer is KILUVHHLI.

The song Vande Mataram, composed in Sanskrit by Bankimchandra Chatterji, was a source of inspiration to the people in their struggle for freedom. It has an equal status with Jana - gana - mana. The first political occasion when it was sung was the 1896 session of the Indian National Congress

Ozone depletion is due to release of CFC (Chloro fluoro carbon) in the atmosphere which result in depletion of Ozone in the stratosphere. The Ozone in the stratosphere protect Living being on Earth from Harmful rays. The other option such as death of animals, Tinnitus and hypertension is due to noise pollution.

Let, speed of the stream = x km/hr

According to the question,

⇒ 55 - x = 40

⇒ x = 15

∴ Downstream speed of the boat = (55 + 15) = 70 km/hr

Tennis is played in a court.

Similarly, boxing is played in a ring.

Let, 6 years ago, age of P = 3x and age of Q = 2x

According to the question,

⇒ (3x + 10)/ (2x + 10) = 8/7

⇒ 21x + 70 = 16x + 80

⇒ 5x = 10

⇒ x = 2

∴ P’s age = 3x + 6 = (3 × 2) + 6 = 12 years

Alternate Method

Concept used:

Basics of ratio and proportion.

Calculation:

Six years ago P ∶ Q =       3 ∶ 2

                                              ↓ 5 unit = (6 + 4 = 10 years)

Four years hence P ∶ Q = 8 ∶ 7

1 unit → 10/5 = 2 years

Age of P after 4 years = 8 × 2 = 16

Present age of P = 16 - 4 = 12 years
