BSF Head Constable Ministerial (HCM) Mock Test - 9 - BSF Head Constable MCQ

The correct answer is 'The problem is how most central banks still tend to function'.
Key Points

• The error lies in the part- 'The problem is how most central banks still tends to function'.
• The subject 'most central banks’ is plural, so 'tends' (which is singular) should be 'tend'.
• The subject and verb must agree in a sentence, meaning that plural subjects need plural verbs and singular subjects need singular forms.
• Therefore, the phrase "most central banks still tends to function" should be rewritten as "most central banks still tend to function".
• Correct sentence- The problem is how most central banks still tend to function under the operative and functional framework, shadowing the work of Milton Friedman.

Therefore, the correct answer is Option A.

The correct answer is 'was acting in accordance with'.
Key Points

• The error lies in the usage of the Simple Past Tense and the preposition 'to'.
• The phrase “in accordance to,” although sometimes seen in informal speech, is grammatically incorrect.
• “In accordance with” is correct when referring to something that we are complying with, such as a law, a contract, or advice.
  • Example - In accordance with your request, I am sending a copy of my book.
• Thus, the phrase 'in accordance' should be followed by preposition 'with' not 'to'.
• Also, 'was acted' needs to be replaced by 'was acting' i.e., the Past Continuous tense.
• The Past Continuous tense is used to denote an action going on at some time in the past. The time of the action may or may not be indicated.
  • Structure of the Past continuous tense: Subject + was/were + ing form of the verb + object.
  • Example - We were listening to the radio all evening.
• Correct sentence: She was acting in accordance with the director's advice.

Hence, the correct answer is option (B).

The correct answer is "Don’t expect that everything you wish will be true."
Key Points:

• The phrase "Don't count your chickens before they hatch" is an idiom in English that advises not to count on things before they happen.
• This phrase suggests that one should not base their plans on future events that may not occur.
• It is closely aligned with the option "Don't expect that everything you wish will be true" because both caution against presuming or predicting outcomes prematurely.
• The other options ("Don’t form an estimation about someone by their exterior," "Don’t risk everything on a single venture," "Do not delay a task if you can do it immediately") do not convey the same meaning as the original idiom.

Therefore, the correct answer is Option D.

The correct answer is 'Sue made many efforts to encourage Johnsy's curiosity about her surroundings.'
Key Points

• Let's have a look at this sentence in the passage:
  • 'Sue tried her best to make Johnsy take an interest in things around her.'
• From the passage, it can be concluded that Sue tried to arouse Johnsy's interest in her surroundings.
• Therefore, the correct answer is Option C.

The correct answer is "blend"
Key Points

• Option A) blend is the most appropriate word to fill in the blank because it accurately describes the architectural style of the Taj Mahal as a combination of different elements. The passage states that the Taj Mahal is a blend of Indian, Persian, and Islamic styles, which suggests that it combines elements from these different styles to create a unique architectural style. A blend is "a mixture of different things, so it is a suitable word to describe the architectural style of the Taj Mahal as a combination of different elements.
• Option B) separation means the "act of separating or the state of being separated", which is not relevant to the architectural style of the Taj Mahal as described in the passage.
• Option C) division means the "act of dividing or the state of being divided", which is not relevant to the architectural style of the Taj Mahal as described in the passage.
• Option D) alloy means a "mixture of two or more different metals", which is not relevant to the architectural style of the Taj Mahal as described in the passage.
• Therefore, option A) blend is the most appropriate word to fill in the blank.

Correct paragraph: The Taj Mahal is a white marble mausoleum located in Agra, India. It was built by the Mughal Emperor Shah Jahan in memory of his beloved wife, Mumtaz Mahal, who died during childbirth. The Taj Mahal is considered one of the finest examples of Mughal architecture, a blend of Indian, Persian, and Islamic styles. It is a UNESCO World Heritage Site and is one of the most visited tourist attractions in the world, with millions of visitors each year.

Given Statements: G > T, H < R, R < T, H = M, M > N

On Combining: N < M = H < R < T < G

Conclusions:

I. N < H → True (As N < M = H, it gives N < H)

II. T > M → True (As M = H < R < T, it gives T > M)

III. R < M → False (As M = H < R, it gives M < R)

IV. G > H → True (As H < R < T < G, it gives G > H)

So, only conclusion III is incorrect.

Hence, the correct answer is "Option C".

The codes have been assigned as follows,

LOST → L = 12 → (12 + 1) = 13; O = 15 → (15 + 1) = 16; S = 19 → (19 + 1) = 20; T = 20 → (20 + 1) = 21;

LOST = 13162021

JUMP → J = 10 → (10 + 1) = 11; U = 21 → (21 + 1) = 22; M = 13 → (13 + 1) = 14; P = 16 → (16 + 1) = 17;

JUMP = 11221417

Similarly,

HIGH → H = 8 → (8 + 1) = 9; I = 9 → (9 + 1) = 10; G = 7 → (7 + 1) = 8; H = 8 → (8 + 1) = 9;

HIGH = 91089

Hence, 91089 is the answer.

All games except Carrom is an outdoor games, while Carrom is an indoor game.

Hence, 'Carrom' is the odd one out.

Calculation:

Convert the given ratios to a common format for easy comparison:

can be written as 3 ∶ 2 (by finding a common multiple).

can be written as 7 ∶ 4 (by finding a common multiple).

From the given ratios, a ∶ b = 3 ∶ 2 and b ∶ c = 7 ∶ 4.

First, make the 'b' term the same in both ratios. The least common multiple (LCM) of 2 and 7 is 14:

a ∶ b = 3 ∶ 2 can be written as 3 × 7 ∶ 2 × 7 = 21 ∶ 14.

b ∶ c = 7 ∶ 4 can be written as 7 × 2 ∶ 4 × 2 = 14 ∶ 8.

Now combine the ratios to get a ∶ b ∶ c:

⇒ a ∶ b ∶ c = 21 ∶ 14 ∶ 8.

∴ The ratio a ∶ b ∶ c = 21 ∶ 14 ∶ 8.

Given:

A can do a work in 24 days. B is 20% less efficient than A. Both A and B worked together for 4 days. B and C working together completed the remaining work in 14 days.

We need to find the time in which A, B, and C together can complete 11/12 part of the original work.

Formula Used:

Efficiency of A = 1/24 work/day

Efficiency of B = (80/100) × Efficiency of A = (80/100) × (1/24) = 1/30 work/day

Let the efficiency of C be C work/day.

Total work = 1 unit

Calculation:

Work done by A and B in 4 days = (1/24 + 1/30) × 4

⇒ (5/120 + 4/120) × 4

⇒ (9/120) × 4

⇒ 3/10 work

Remaining work = 1 - 3/10

⇒ 7/10 work

Work done by B and C in 14 days = 7/10

(1/30 + C) × 14 = 7/10

⇒ (1/30 + C) = (7/10) / 14

⇒ (1/30 + C) = 7/140

⇒ 1/30 + C = 1/20

⇒ C = 1/20 - 1/30

⇒ C = (3 - 2) / 60

⇒ C = 1/60 work/day

Efficiency of A, B, and C together = 1/24 + 1/30 + 1/60

⇒ Efficiency = (5 + 4 + 2) / 120

⇒ Efficiency = 11/120 work/day

⇒ Time = (11/12) × (120/11)

⇒ Time = 10 days

∴ The correct answer is 10 days (D).

Given:

Total products produced by factory workers = 100

He gets Rs 10 for producing each piece of this product.

On day 1, he produces 1/10th of what he was supposed to produce.

On day 2, he produces 1/10th of the number of remaining products.

Calculation:

According to the question

Each piece of this product produced by factory workers = Rs. (100 × 10) = Rs. 1000

On day 1, he produces 1/10th of what he was supposed to produce.

⇒ Rs. (1000 × 1/10) = Rs. 100

Remaining products = (1000 - 100) = 900

On day 2, he produces 1/10th of the number of remaining products

⇒ Rs. (900 × 1/10) = Rs. 90

Total income earned by A by the end of day 2 = Rs. (100 + 90)

⇒ Rs. 190

∴ The required income earned by A is Rs. 190

Given set of numbers is 2, 7, 5, 6, 7, 5, 4, 4, 0, 3, 0, 3, 1, 1, 3

Concept used:

The following steps are helpful while applying the median formula for ungrouped data.
Step 1: Arrange the data in increasing order.
Step 2: Secondly, count the total number of observations 'n'.
Step 3: Check if the number of observations 'n' is even or odd.

Median Formula When n is Odd

Median = [(n + 1)/2]th term

Calculation:

The numbers in increasing order = 0, 0, 1, 1, 2, 3, 3, 3, 4, 4, 5, 5, 6, 7, 7

Total number of terms = 15 which is odd term

So, median = [(15 + 1)/2]^th term

⇒ (16/2)^th term

⇒ 8^th term

8th term of the numbers is 3

∴ The median of the numbers is 3.

Calculation:

4/5  of 70 =4/5 x 70   = 4 × 14 = 56

5/7  of 112 =5/7 x 112   = 5 × 16 = 80

80 - 56 = 24

 4/5 of 70 is how much percent less than 5/7  of 112:

24/80 x 100 = 30%

Hence, '30' is the correct answer.

Calculation:

Distance between A and B = 220 km

A starts moving towards B at 11 AM with speed of 40 km/hr

B starts moving Away from A at 12 PM with speed of 30 km/hr

At 12 PM A travelled 40 km

Now distance reduced to 180 km

Now both starts moving and difference between their speed is 10 km/hr

Since A’s speed is 10 km more than B so they will meet after 180 km / 10 km/hr = 18 hr = at 6 AM on next day

∴ Option 4 is the correct answer.

Given:

Diameter of wheel = 21 cm

Speed 16.5 km/h

Formula used:

Distance = Time × Speed.

R = Dimeter / 2

Distance of one Revolution = 2 × (22 / 7) × R

Total number of revolution = Total Distance / Distance of one revolution.

Calculation:

Distance = Time × Speed

⇒ (45 / 60) × 16.5 Km/h

⇒ 12.375 Km.

Change in cm = 12.375 × 1000 × 100

⇒ 1237500 cm

Distance in one revolution = 2 × (22 / 7) × 21 / 2

⇒ 66 cm

Number of Revolutions = 1237500 / 66

⇒ 18750

Number of Revolutions = 18750
