RRB NTPC Previous Year Paper Tier-I 2016 (Set 1) - RRB NTPC/ASM/CA/TA MCQ

In figure (2), (3), (4) we have 4 compartments but in (1) we have only 2 compartments.
Hence, figure (1) is different from other three figure. 

Part of the tank filled in one min = 1/20
Part of the tank emptied in one min = 1/60

⇒ Part of the tank to be filled due to leakage in one min = 1/20 - 1/60 = 2/60 = 1/30
∴ Tank will be filled in 30 minutes

The National AQI is published for every month by CPCB along with a numerical value and a colour code which helps in comparing air pollution levels in cities. It is determined on the basis of concentration of 8 pollutants, including Particulate Matter (PM 2.5, PM 10), sulphur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), ozone (O3), ammonia (NH₃) and lead (Pb).

Sum of the given numbers = 2 + 2 + 2 + 4 + 6 + 7 = 23
Mean of the given values = 23/6 = 3.83

Leprosy, also known as Hansen's disease (HD), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. It is not clear how the leprosy germ is spread, but household and prolonged close contact is necessary. The germs probably enter the body through the nose and possibly through broken skin. The germs get in the air through nasal discharge of untreated lepromatous patients.

The Indian Antarctic Program is a multi-disciplinary, multi-institutional program under the control of vedant National minister for Antarctic and Ocean Research, Ministry of Earth Sciences, Government of India. It was initiated in 1981 with the first Indian expedition to Antarctica.
The program gained global acceptance with India's signing of the Antarctic Treaty and subsequent construction of the Dakshin Gangotri Antarctic research base in 1983, superseded by the Maitri base from 1990. The newest base commissioned in 2015 is Bharati, constructed out of 134 shipping containers

From the given data,
⇒ 2² – 3³ + 4³ – 6² = 4 - 27 + 64 - 36 = 5

Intaglio printing is the opposite of relief printing, in that the printing is done from ink that is below the surface of the plate.
The design is cut, scratched, or etched into the printing surface or plate, which can be copper, zinc, aluminum, magnesium, plastics, or even coated paper.

Biogas is a mixture of different gases, major portion in biogas being methane (CH₄) and carbon dioxide (CO₂). It also contains traces of other gases like hydrogen (H₂), Moisture (H₂O) , hydrogen sulphide (H₂S)etc. Improved digesters used for anaerobic digestion can produce biogas with 65% - 75% methane content.

We can represent above given information in family diagram,

Therefore Oldman will be Surdas father.

The lentil (Lens culinaris) is an edible pulse. It is a bushy annual plant of the legume family, known for its lens-shaped seeds. It is about 40 cm (16 in) tall, and the seeds grow in pods, usually with two seeds in each. In South Asian cuisine, split lentils (often with their hulls removed) are known as lentils.

Here, except lentil, the other three are the leafy vegetables.

In SEVEN is coded as TFWFO

Now in “EIGHT” will be coded as,

Hence, “EIGHT” will be coded as “FJHIU”.

A generator is a device that converts mechanical energy to electrical energy for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines and even hand cranks.

InDIGO or IndIGO or LIGO  is a consortium of Indian gravitational-wave physicists. This is an initiative to set up advanced experimental facilities for a multi-institutional observatory project in gravitational-wave astronomy.

The Lasoong festival is the most popular festival of Sikkim. It is usually celebrated at the end of the tenth Tibetan lunar month (usually December). It is the most important festival among the Bhutias in India and is marked by the traditional Chaan dancing and merry-making

We know that area of the circle = π × r² = π × [(28)/2]² = 616 sq.m
∴ Cost of leveling circular ground = 616 × 125 = Rs. 77, 000

Let the numbers be 2x and 3x
LCM of 2x and 3x = 6x
Given that LCM = 66
⇒ 6x = 66
⇒ x = 66/6 = 11
∴ The numbers are 22 and 33
∴ Sum of the numbers = 22 + 33 = 55

Cost price of 10 kg of rice = Rs. 400 × 10 = Rs. 4000

Cost price of 5 kg of rice = Rs. 2000 and the cost price of the remaining 5 kg of rice = Rs. 2000

Also given that trader got 20% loss for half of the quantity

We know that loss% = (CP - SP)/CP × 100
⇒ 20 = (2000 - SP)/2000 × 100
⇒ 200000 - 40000 = 100SP
⇒ SP = Rs. 1600
∴ Loss for first half = 2000 - 1600 = Rs. 400

Also given that profit for second half is 10%
⇒ 10 = (SP - 2000)/2000 × 100
⇒ 100SP = 20000 + 200000
⇒ SP = 2200
∴ Profit for second half = 2200 - 2000 = Rs. 200
∴ Net there is a loss of Rs. 200
Final loss % = (net loss/total cost price × 100) = 200/4000 × 100 = 5%

Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom.
It serves as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol.

In SUFFIX is coded as USFFXI

Similarly, LONDON will be coded as,

Therefore “LONDON” will be coded as “OLDNNO”.

The above information we can represent in family diagram,

Sam’s brother’s father is also Sam’s father.
Here we cannot determine gender of “Samridhi” is either brother or sister of “Sam”.
As we can see there in no option of Brother among all available option.
Hence sister will be correct option.

Drawing a Venn diagram of given statements,

Conclusions:
1. No fan is a T.V → True
2. All computers are T.V → False (it’s possible but not definite, hence false.)
3. Some computers are T.V → False (it’s possible but not definite, hence false.)
4. All refrigerators are fans → False (it’s possible but not definite, hence false.)
Therefore only conclusion 1 will follows. 

Ban Ki-moon is a South Korean diplomat who was the eighth Secretary-General of the United Nations from January 2007 to December 2016.

If GREECE is coded as 634454 and PART is coded as 7231

Therefore code for “TERRACE” will be “1433254”.

If BOARD is coded as 45136 and CHALK is coded as 78129

BLOCK = 42579
Therefore “BLOCK” will be coded as “42579”.

From the given data,

Total rainfall of JK for 4 months = 1100 + 1100 + 1000 + 1200 = 4400

Total rainfall of HP for 4 months = 1100 + 1100 + 1000 + 1300 = 4500

Total rainfall of WB for 4 months = 1400 + 1300 + 1200 + 1000 = 4900

Total rainfall of GA for 4 months = 1000 + 1300 + 1500 + 1700 = 5500

Total rainfall of TN for 4 months = 1200 + 1050 + 1000 + 1100 = 4350

∴ Rainfall is lowest for TN

Total rainfall for the month of June of five states = 1100 + 1100 + 1400 + 1000 + 1200 = 5800

Total rainfall for the month of July of five states = 1100 + 1100 + 1300 + 1300 + 1050 = 5850

Total rainfall for the month of August of five states = 1000 + 1000 + 1200 + 1500 + 1000 = 5700

Total rainfall for the month of September of five states = 1200 + 1300 + 1000 + 1700 + 1100 = 6300

∴ Rainfall is lowest for the month of August

From the given data,

Increase of rainfall for JK from June to September = (1200 - 1100) = 100

Increase of rainfall for HP from June to September = (1300 - 1100) = 200

Increase of rainfall for WB from June to September = (1000 - 1400) = - 400

Increase of rainfall for GA from June to September = (1700 - 1000) = 700

Increase of rainfall for TN from June to September = (1100 - 1200) = - 100

∴ GA shows the gradual increase in its rainfall from June to September

We know that a : b : : c : x, then x = bc/a
⇒ Fourth proportional x = (17 × 27)/9 = 51

Let the number of men who agreed to do the work in 20 days be x
⇒ work done by x men = 20x
Also given (x - 5) men will complete the work in 40 days
⇒ work done by (x - 5) men = 40(x - 5)
Since the work done by both are same
⇒ 20x = 40(x - 5)
⇒ 20x - 40x = - 200
⇒ x = 10
∴ No of men who had agreed to do the work originally = 10
