RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - RRB NTPC/ASM/CA/TA MCQ

As per the given data,

Let the cost price of the pen be Rs.x

⇒ Profit % = (SP - CP)/CP × 100

⇒ 20 = (36 - x)/x × 100

⇒ 20x = 3600 - 100x

⇒ 120x = 3600

⇒ x = 30

∴ Cost price of the pen is Rs.30

Also given that he sold the pen at Rs.33

By comparing with cost price of the pen Rs.30 with selling price of the pen Rs.33, we can say it as profit

⇒ Profit % = (33 - 30)/30 × 100 = 10 %

∴ Percentage of profit is 10%

• The two liquids that can't dissolve in each other or the two liquids in which diffusion can't takes place are called immiscible liquids. They can’t form homogeneous mixtures.For example- Water and oil.
• When two liquids can be mixed to form homogeneous mixtures they are called miscible liquids.

For example- Alcohol and water.

Extra Information:

Let the angles of a triangles are in the ratio of x : 4x : 7x

We know that sum of the angles in a triangle = 180°

⇒ x + 4x + 7x = 180°

⇒ 12x = 180

⇒ x = 15°

∴ Smallest angle = 15°

Greatest angle = 7x = 7(15) = 105°

Ratio of the greatest angle to the smallest angle = 105 : 15 = 7 : 1

⇒ 9876 + 34.567 - ? = 9908.221

⇒ 9910.567 - ? = 9908.221

⇒ ? = 9910.567 - 9908.221 = 2.346

EARSUQ → SQUARE → An equally four sided geometrical shape.

ONGPOYL → POLYGON → A multiple sided geometrical shape.

NAEGRCELT → RECTANGLE → A four sided geometrical shape with two sides having equal length and other two sides having equal breadth.

RGETESNH → GREENTHS → The green growth or verdure. The greenery of anything.

Clearly, RGETESNH is not related to mathematics and is the odd one out.

• Graf won 22 Grand Slam singles titles; in 1988, she had a "Golden Slam," winning all four major competitions and Olympic gold in one calendar year.
• Graf retired from tennis in 1999.

Let the present age of vikas and Rahul be x and y

Given that 4 years ago, the ratio of Vikas’s to Rahul’s age was 3 : 5

⇒ (x - 4)/(y - 4) = 3/5

⇒ 5x - 20 = 3y - 12

⇒ 5x - 3y = 8          ----equation (1)

Also given that after 6 years, this ratio would become 4 : 5

⇒ (x + 6)/(y + 6) = 4/5

⇒ 5x + 30 = 4y + 24

⇒ 5x - 4y = - 6          ----equation (2)

By subtracting equation (2) from equation (1), we get

y = 14

∴ Present age of Rahul y = 14 years

• The planet Venus is almost equal in size to the planet Earth. The radius of planet Earth is 6,371 km, whereas the radius of Planet Venus is 6,052 Km.
• Both Earth and Venus are rocky planets, which has almost the same density. The Earth and Venus often known as planetary twins, only because of the similarity in size and mass.

Let the required number be x

⇒ 40 =  × 100

⇒ 2/5 = 7/x - 1

⇒ 2/5 + 1 = 7/x = 7/5 = 7/x

⇒ x = 5

∴ He has to sell 5 pair of clips for a rupee to get profit of 40%

• Mudrarakshasa means (“Minister Rakshasa and His Signet Ring”).
• The Mudrarakshasa is a historical play in Sanskrit byVishakhadatta.
• He dramatized the paradox that a ruler has to have complete confidence in the minister who is ruling his state.
• It narrates the ascent of the king Chandragupta Maurya to power.
• The title Mudrarakshasa refers to the signet ring of Rakshasa which was stolen by Chanakya’s spy.
• Chanakya was reportedly the chief minister to the Chandragupta Maurya.

Did you know:Arthsastra is attributed to Chanakya.

As per the given data,

Let the cost price be Rs. 100, then marked price = Rs.150

Given required gain = 10%

∴ Selling price = Rs. 110

We know that discount = Marked price - selling price

So, discount = 150 - 110 = 40

Discount percentage = 40/150 × 100 = 26.66% (nearly 27%)

• At the time of independence , there were around 565 pricely states which were ruled by different kings and were not formally part of the British.
•  Rest of the regions made up for the British India.
• The British India had 17 Provinces and 565 princely states, before 1947.

• Milk of Magnesia is another name for magnesium hydroxide.
• Milk of Magnesia is used as a laxative to relieve occasional constipation (irregularity) and as an antacid to relieve indigestion, sour stomach, and heartburn.

Given that (7x + 5)° and (x + 5)° are complementary angles

⇒ (7x + 5) + (x + 5) = 90°

⇒ 8x + 10 = 90

⇒ 8x = 80

⇒ x = 10

∴ The value of x is 10

Correct Answer :- A

Explanation : The Seventh Schedule to the Constitution of India defines and specifies allocation of powers and functions between Union & States.

The logic followed is:

3⁵ = 243. Therefore, 5⁵ = 3125

Hence, the correct answer is 3125.

• The American scientist Benjamin Franklininvented bifocals .
• Bifocals are eyeglasses with two distinct optical powers.
• Bifocals are commonly prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and/or astigmatism.

• Cheetahs are the world’s fastest land animal, capable of reaching speeds of up to 70 mph.
• Cheetahs are also very fast accelerators, and can ramp up their speed four times faster than human beings can.
• Cheetahs are currently classified as “vulnerable” by the IUCN.

Let the number be x

⇒ 70% of 5/7^th of x = 90

⇒ 70/100 × 5/7 × x = 90

⇒ 350/700 × x = 90

⇒ x = 90 × 700/350 = 180

• PDA stands for Personal Digital Assistant, a handheld device that combines computing, telephone/fax, Internet and networking features.
• A typical PDA can function as a cellular phone, fax sender, Web browser and personal organizer.

SAMR → MARS → a planet.

MOETC → COMET → an icy astronomical bodies.

USVNE → VENUS → a planet.

PUJIERT → JUPITER → a planet.

Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune are planets in our solar system.

Comets are icy bodies in space that release gas or dust.

Therefore, MOETC is the odd one out.

As per the given data,

Length of the circular track = π × d = π × 28 m

Given that Pihu and Aayu are running in the same direction at the same point

We know that when two persons A and B running around a circular track of length L mts with speed of a, b m/s in the same direction

They meet each other at any point on the track = L/(a - b) sec

= 28 π/(48 - 40)

= 11 sec

• A hypothesis is a suggested explanation for an observable phenomenon among multiple phenomena.
• A theory is a tested, well-substantiated explanation for a set of verified, proven factors.
• When hypothesis are confirmed by varied tests then it becomes theory.

As per the given data,

We know that dividend = divisor × quotient + remainder

⇒ 11509 = divisor × 71 + 7

⇒ 11502 = divisor × 71
