RRB NTPC Mock Test - 16 (English) - Railways MCQ

Ally means to merge or friend, opposite of enemy, likewise ancient is opposite of Modern.

Hence, Ancient : Modern is the correct answer.

• MIPS stands for Million Instructions Per Second.
• BPS stands for Bits Per Second. It is a standard way to measure data transfer rates.
• Baud is used to describe the maximum oscillation rate of an electronic signal.

• Chucker is related to Polo.
• Chucker is a term used in Polo to define a time segment like halves or quarters in other games like football.
• The normal duration of chukka/chucker is 7-minutes after 7 minutes of play continues for an additional 30 seconds or until a stoppage in play.
• There are six or more chucker in one polo match.

Let the speed of the stream = x km/hr

Given,

Speed of the boat in still water = 50 km/hr

∴ Speed of the boat towards upstream = (50 - x) km/hr

Distance covered = 500 km

Time taken = 20 hr

∵ Distance covered = Speed × Time taken

⇒ 500 = (50 - x) × 20

⇒ 25 = (50 - x)

⇒ x = 25 km/hr

• Jaishankar Prasad was the author of the book “Kamayani”.
• Kamayani is a Hindi epic poem.
• It is considered one of the great literary works written in modern times in Hindi Literature.
• It also signifies the epitome of Chhayavai school of Hindi poetry gained popularity in the late 19th and early 20th centuries.

Consider the following least possible Venn diagram,

Conclusions:

I. All blue are yellow → False (It is possible but not definite).

II. Some black are yellow → True (It is definitely true as the part of blue which are yellow is also black as all blue are black).

Hence, only conclusion II follows.

• On 15 November 2000 Jharkhand became the 28th state of India, separated from Bihar.
• On 9 November 2000 Uttarakhand became the 27th state of India and was separated from Uttar Pradesh.
• On 1 November 2000 Chhattisgarh became the 26th state of India and was separated from Madhya Pradesh
• On 2 June 2014 Telangana was separated from the Andhra Pradesh to form the newly formed 29th state.

Total number of candidates = 120

Let the number of candidates who passed the exam be = x

No. of failed candidates = (120 - x)

Then total marks = 120 × 35 = 39x + (120 - x) × 15

⇒ 4200 = 39x + 1800 - 15x

⇒ 4200 - 1800 = 24x

∴ x =  2400/24  = 100

The relation among the given numbers is:

93 + 9 = 102

102 + 8 = 110

110 + 7 = 117

117 + 6 = 123

123 + 5 = 128

128 + 4 = 132

Hence, “117” is the missing term.

• Sri Lanka’s first satellite ‘Raavana-1’ was launched into space from NASA’s Flight Facility on Virginia’s east shore.
• The satellite was designed and built at the Kyushu Institute of Technology in Japan by two Sri Lankan research engineers.

1) MELAC → CAMEL

2) RITEG → TIGER

3) ROSHE → HORSE

4) UFBAFOL → BUFFALO

Except 'Tiger' all are herbivores whereas 'Tiger' is a carnivore.

Hence, 'Tiger' is the odd one.

Difference of consecutive terms: 2,3,4,5,6,7,8……

We can see that the difference of consecutive terms in the sequence are in AP with first term 2 and common difference = 1.

∴ n^th term of this sequence (1,3,6,10,……) is given as, a_n = a_(n - 1) + (2 + (n - 2)d), n ≥ 2.

Now, a₅ = a₄ + (2 + (5 - 2)1) = 10 + (2 + 3) = 10 + 5 = 15

a₆ = a₅ + (2 + (6−2)1) = 15 + (2+4) = 15  + 6 = 21
a₇ = a₆ + (2 + (7−2)1) = 21+(2+5) = 21 + 7 = 28

Now, a₆/a₇ = 21/28 = 3/4

⇒ a6:a7=3:4

• Gerontology is known as the study of old age.
• Gromatici is known as the science of surveying.
• Gynaecology is known as the study of women’s physiology.
• Gyrostatics is known as the study of rotating bodies.

Option 4 is the correct answer. As we see in the statement, Rajiv Sharma is dissatisfied with his salary and perks, So he joins another company. The inference I is about the new company giving good salary to all its employees, which is not mentioned in the statement. Hence, I does not follow here. The inference II talks about present company's condition about which no information is given in the statement. So, both inferences do not follow.

• Carbon monoxide is formed by a coordinate bond.
• A covalent bond is formed by two atoms sharing a pair of electrons.
• A coordinate bond is a type of covalent bond where both of the electrons that form the bond originate from the same atom.
• Carbon monoxide has two ordinary covalent bonds between the carbon and oxygen and also a coordinate bond using a lone-pair on the oxygen atom.

SI unit of Work is Joule.

Similarly, SI unit of Power is Watt.

Hence Power is related to Watt.

• The king of England Charles II got Bombay as dowry for marrying Catherine in 1661 AD.
• According to the marriage treaty of Charles II of England and Catherine of Braganza, daughter of King John IV of Portugal on 21 May 1662, placed Bombay in possession of the British Empire.
• Currently, Bombay is the capital city of Maharashtra.
• It is also known as the financial capital of India.
• According to the 2011 census, It was the most populous city of India.

• Keratin is a fibre protein. This protein is found in hair, nail, horn, wool etc.
• It also protects epithelial cells from damage or stress.

[(a^-2b³) ÷ (a¹b^-1)] × [(a²b^-4) ÷ (a^-1b²)]

Using BODMAS rule a^m ÷ aⁿ = a^{m - n}

[(a^-2b³) ÷ (a¹b^-1)] × [(a²b^-4) ÷ (a^-1b²)]

= a^{-2 - 1}b^3-(-1) × a^2-(-1)b^{-4 - 2}

a^-3b⁴ × a³b^-6

a^m × aⁿ = a^{m + n}

= a^{-3 + 3}b^{4 - 6}

= b^-2

= 1/b²

Given sinB = (5/13) = Perpendicular/hypotenuse

⇒ We know that (Hypotenuse)² = (Perpendicular)² + (Base)²

⇒ (13)² = (5)² + (Base)²

⇒ (Base)² = (13)² - (5)²

⇒ (Base)² = 169 - 25

⇒ (Base)² = 144

⇒ (Base) = √144

⇒ (Base) = 12

⇒ cosB = Base/hypotenuse = 12/13

⇒ tanB = Sin B/Cos B

⇒ tanB = (5/13)/(12/13)

⇒ tanB = 5/12

⇒ cosecB = (1/Sin B) = (13/5)

⇒ tanB + cosecB = (5/12) + (13/5)

⇒ (25 + 156)/60

⇒ 181/60

∴ Required value is 181/60

Let us assume the one of the numbers as x and the other as y,

⇒ x + y = 32    ---- (I)

⇒ x × y = 156

⇒ x = 156/y    ----(II)

Substitute the value of Eq(II) in Eq(I),

⇒ (156/y) + y = 32

⇒ 156 + y² = 32y

⇒ y² – 32y + 156 = 0

⇒ (y – 6)(y – 26) = 0

⇒ y = 6 or 26

Let us consider y = 6,

Value of x = 156/6 = 26

Factors of 6 = 3 × 2 = 2, 3

Factors of 26 = 13 × 2 = 2, 13

∴ HCF(6, 26) = 2

Given equation is 54 ÷ 6 × 2 - 10 × 4 = 82

Let’s check each option,

1. 54 ÷ (6 × 2) - 10 × 4 = 54 ÷ 12 - 40 = - 35.5 ≠ 82

2. 54 ÷ 6 × 2 - (10 × 4) = 9 × 2 - 40 = - 22 ≠ 82

3. 54 ÷ 6 × (2 - 10) × 4 = 9 × (- 8) × 4 = - 288 ≠ 82

4. (54 ÷ 6) × 10 - 4 × 2 = 9 × 10 - 8 = 82

Hence, (54 ÷ 6) × 10 - 4 × 2 is the correct option.

Sum of all the interior anglesof a polygon having 12 sides = 180(12 – 2) = 180 × 10 = 1800°

6 – 36 × 3 ÷ 6 + 5 = 6 – 18 + 5 = -7

∴ ? = -7

According to the given condition ,

90% of M.P = 125% of CP

∴ M.P = (1.25 × 600)/0.9 = 833.33

∴ The marked price of the camera would be Rs 833.33

A bunch is a group of the same things.

Similarly,

A group of sheep is called a flock, herd or mob.

Thus Sheep is related to Flock.

Speed of sound = 342 m/s.

Time taken for hearing an echo = 2s.

Distance travelled = 2d = v × t

2 × d = 342 × 2

d = (342 × 2)/2

= 342 m

• Infrasonic is the sound waves below the frequencies of audible sound i.e. below 20 Hz.
