Open Market Operation

The correct answer is Open Market Operation.

Key Points

  • Open Market Operation (OMO) refers to the buying and selling of government bonds and securities by a central bank (e.g., the Reserve Bank of India - RBI) in the open market.
  • OMOs are conducted to regulate the money supply and liquidity in the economy, ensuring price stability and growth.
  • When the central bank buys government bonds, it injects liquidity into the economy by increasing the money supply, which is often done during periods of economic slowdown.
  • Conversely, when the central bank sells government bonds, it absorbs excess liquidity from the market, helping control inflation during periods of economic overheating.
  • OMOs play a crucial role in implementing the monetary policy of a country, aimed at achieving macroeconomic objectives such as controlling inflation, stabilizing the currency, and fostering economic growth.

Additional Information

  • Liquidity Adjustment Facility (LAF):
  • LAF is a monetary policy tool used by the RBI to manage liquidity in the economy and control short-term interest rates.
  • It comprises repo and reverse repo operations, where banks borrow or lend funds to the RBI against collateral.
  • This tool is used to address short-term liquidity mismatches in the banking system.
  • Bank Rate:
  • The bank rate is the interest rate at which the RBI lends funds to commercial banks without requiring any collateral.
  • It is a long-term rate used to influence credit availability and regulate inflation or deflation.
  • An increase in the bank rate discourages borrowing and helps control inflation, while a decrease has the opposite effect.
  • Marginal Standing Facility (MSF):
  • MSF is a facility provided by the RBI that allows banks to borrow overnight funds at a rate higher than the repo rate.
  • It is intended to provide emergency liquidity to banks in times of severe cash shortages.
  • The MSF rate is usually set above the repo rate, encouraging banks to manage liquidity efficiently.
  • Additional Facts About Open Market Operation:
  • OMOs are conducted by the RBI through auctions using an electronic trading platform called Negotiated Dealing System-Order Matching (NDS-OM).
  • During the COVID-19 pandemic, the RBI conducted special OMOs, also known as "Operation Twist," to manage the yield curve effectively.
  • OMOs are considered a crucial component of quantitative easing in advanced economies, such as the United States and the European Union.

Important Points

  • Key Differences Between Repo Rate and OMO:
  • Repo Rate: A short-term tool where banks borrow funds from the RBI by selling securities with an agreement to repurchase them later.
  • OMO: A broader tool involving the outright purchase or sale of government bonds to manage the money supply.

Show Answer
Answer: ((d))

PQRS

The correct answer is '4' i.e. PQRS .

Key Points

  • The paragraph opens with P, which introduces the commonly held belief that leaders need to be gregarious.
  • Next, Q provides a counterpoint, stating that leadership effectiveness depends on other factors, like the personalities of employees.
  • Then comes R, which gives evidence from a study showing extroverted bosses perform well with passive employees.
  • Finally, S concludes with the contrasting finding that introverted leaders excel with proactive employees.

Correct sentence: PQRS forms the most logical and coherent sequence for the paragraph.

Additional Information

  • Logical Flow: Start with the general belief (P), introduce a counterpoint (Q), provide evidence (R), and end with a contrasting finding (S).
  • This sequence ensures the paragraph is clear, logical, and easy to follow.

RSPQ

The correct answer is '4' i.e. RSPQ .

Key Points

  • The question asks us to rearrange the four parts (P, Q, R, S) of a sentence/passage into a logical and coherent order.
  • When analyzing the given parts, the sequence RSPQ makes the most logical sense:
  • R: "His wife passed him the piece of parchment." (The action starts here with the wife handing the parchment.)
  • S: "He took it and glanced at it, meaning to pass it back with a scornful remark." (The husband reacts to the parchment.)
  • P: "What did these children know about old things?" (A rhetorical question that implies the content of the parchment.)
  • Q: "It was probably a bit of an old letter blown about by the wind, that they had picked up in the street." (This explains the parchment's origin.)

Correct sentence: "His wife passed him the piece of parchment. He took it and glanced at it, meaning to pass it back with a scornful remark. What did these children know about old things? It was probably a bit of an old letter blown about by the wind, that they had picked up in the street."

Additional Information

  • Rearranging sentences:
  • Start with the introductory action or subject (who/what is involved).
  • Follow the sequence of events logically (chronological or cause-effect). Look for connecting ideas or pronouns.
  • End with concluding remarks or explanations.
  • Tip: Look for key words or phrases that indicate sequence (e.g., "he took it," "it was," "what did..."). These help in determining the logical order.

Chosen carefully by the researchers, the oils may not only palliated the condition, but also cure it.

  1. ((a))

    Chosen carefully by the researchers,

  2. ((b))

    the oils may not only palliated

  3. ((c))

    the condition, but also cure it.

  4. ((d))

    No error

Show Answer
Answer: ((b))

the oils may not only palliated

The correct answer is '2' i.e. the oils may not only palliated .

Key Points

  • The sentence contains an error in the use of the verb "palliated" in part 2.
  • The auxiliary verb "may" is followed by the base form of the verb, not a past-tense verb.
  • Thus, "palliated" should be replaced with "palliate" to maintain grammatical correctness.
  • The corrected phrase would be: "the oils may not only palliate the condition, but also cure it."

Correct sentence: Chosen carefully by the researchers, the oils may not only palliate the condition, but also cure it.

Additional Information

  • Use of Modal Verbs:
  • Modal verbs like "may," "can," "will," "should," etc., are always followed by the base form of the verb.
  • Example: She can dance (not "can danced").
  • Parallelism:
  • In sentences with "not only...but also," the structure on both sides should be grammatically parallel.
  • Here, "palliate" and "cure" are both in their base form, maintaining parallelism.

The correct answer is '2' i.e. that was to making the young .

Key Points

  • The given sentence contains a grammatical error in segment 2: that was to making the young.
  • The phrase "to making" is incorrect because "to" should be followed by the base form of the verb, not the gerund form.
  • The correct phrase is "to make".

Correct sentence: At seven began the education that was to make the young boy a citizen and a soldier.

Additional Information

  • Gerund vs. Infinitive:
  • Gerund: A verb form ending in "-ing" used as a noun (e.g., "making").
  • Infinitive: The base form of a verb, often preceded by "to" (e.g., "to make").
  • In this case, the infinitive is required because "to" indicates purpose or intention.
  • Usage Tip: Avoid using the gerund form when "to" is used as part of an infinitive structure.

    the lives of

  3. ((c))

    farmer’s

  4. ((d))

    practice agriculture

Show Answer
Answer: ((c))

farmer’s

The correct answer is '3' i.e. farmer’s .

Key Points

  • The error lies in the segment "farmer’s."
  • The apostrophe in farmer’s indicates possession, but in this context, the plural form farmers is required without the apostrophe.
  • The sentence is discussing multiple farmers who practice agriculture, not possession by a single farmer.

Correct sentence: Scholars have studied the lives of present-day farmers who practice agriculture.

Additional Information

  • Usage of Apostrophes:
  • To show possession: Add an apostrophe + "s" for singular nouns (e.g., farmer’s land).
  • For plural nouns: Add an apostrophe after "s" if the plural noun already ends in "s" (e.g., farmers’ union).
  • No apostrophe: For plural nouns without possession (e.g., farmers work hard).
  • Importance of Context: Always check if the noun refers to singular possession or plural form to avoid grammatical errors.

Correct sentence: His success as a lawyer grew so fast that he soon had enough money to buy a house.

Additional Information

  • Adjective vs. Noun:
  • Adjective: Describes a noun (e.g., successful).

Rivers has being of primary importance throughout human history.

  1. ((a))

    Rivers

  2. ((b))

    has being

  3. ((c))

    throughout

  4. ((d))

    history

Show Answer
Answer: ((b))

has being

The correct answer is '2' i.e. has being .

Key Points

  • The verb phrase "has being" is grammatically incorrect. The correct phrase should be "has been", as "has been" indicates a present perfect form which is appropriate for describing something that has continued up to the present.
  • The subject "Rivers" is plural, so the sentence should use the plural auxiliary verb "have been" instead of "has been." However, correcting just the error in the segment "has being" is sufficient in this context.

Correct sentence: Rivers have been of primary importance throughout human history.

Additional Information

  • Present Perfect Tense:
  • Structure: Subject + has/have + past participle.
  • Example: She has been to the museum several times.
  • Usage: Describes actions or events that began in the past and continue up to the present, or have relevance to the present moment.
  • Common Errors:
  • Mixing up "being" and "been." "Being" is used for continuous forms, while "been" is used for perfect forms.
  • Incorrect auxiliary verb usage with plural or singular subjects.

Difference in the speed of two trains A and B is 35 km/hr. If A takes 3 hours less time to travel a distance of 300 km than train B takes to travel a distance of 200 km. Find the sum of their speeds.

  1. ((a))

    75 km/hr

  2. ((b))

    85 km/hr

  3. ((c))

    95 km/hr

  4. ((d))

    105 km/hr

Show Answer
Answer: ((b))

85 km/hr

Given:

Difference in speed = 35 km/hr

Distance traveled by A = 300 km

Distance traveled by B = 200 km

A takes 3 hours less time than B

Formula used:

Time = Distance ÷ Speed

Let speed of B = x km/hr

Speed of A = x + 35 km/hr

Calculation:

⇒ Time taken by B = 200 ÷ x

⇒ Time taken by A = 300 ÷ (x + 35)

⇒ 200 ÷ x - 300 ÷ (x + 35) = 3

⇒ (200(x + 35) - 300x) ÷ x(x + 35) = 3

⇒ (200x + 7000 - 300x) ÷ x(x + 35) = 3

⇒ (-100x + 7000) ÷ x(x + 35) = 3

⇒ -100x + 7000 = 3 × x(x + 35)

⇒ -100x + 7000 = 3x2 + 105x

⇒ 3x2 + 105x + 100x - 7000 = 0

⇒ 3x2 + 205x - 7000 = 0

Solving using factorization:

⇒ 3x2 + 245x - 40x - 7000 = 0

⇒ x(3x + 245) - 40(3x + 245) = 0

⇒ (x - 40)(3x + 245) = 0

⇒ x = 40 (since speed cannot be negative)

⇒ Speed of B = 40 km/hr

⇒ Speed of A = 40 + 35 = 75 km/hr

⇒ Sum of speeds = 40 + 75 = 115 km/hr

∴ The correct answer is option (2).

A car covers four successive 8 km distance at speed of 10 kmph, 20 kmph, 30 km/hr and 60 kmph respectively. Its average speed over this distance is:

  1. ((a))

    20 kmph

  2. ((b))

    30 kmph

  3. ((c))

    45 kmph

  4. ((d))

    50 kmph

Show Answer
Answer: ((a))

20 kmph

Given:

Distances: 4 × 8 km

Speeds: 10 kmph, 20 kmph, 30 kmph, 60 kmph

Formula used:

Average Speed = Total Distance / Total Time

Calculations:

Total Distance = 4 × 8 = 32 km

Total Time = (8/10) + (8/20) + (8/30) + (8/60)

⇒ Total Time = 0.8 + 0.4 + 0.267 + 0.133

⇒ Total Time = 1.6 hours

Average Speed = Total Distance / Total Time

⇒ Average Speed = 32 / 1.6

⇒ Average Speed = 20 kmph

∴ The correct answer is option (1).

    15 years

  2. ((b))

    17 years

  3. ((c))

    18 years

  4. ((d))

    19 years

Show Answer
Answer: ((d))

19 years

Given:

Total students = 35

Average age of all students = 16 years

Average age of 21 students = 14 years

Formula used:

Total age = Average × Number of students

Remaining students' average = Remaining total age ÷ Remaining number of students

Calculations:

Total age of 35 students = 16 × 35

⇒ Total age = 560

Total age of 21 students = 14 × 21

⇒ Total age = 294

Remaining total age = 560 - 294

⇒ Remaining total age = 266

Remaining number of students = 35 - 21

⇒ Remaining students = 14

Remaining students' average = 266 ÷ 14

⇒ Remaining students' average = 19

∴ The average age of the remaining 14 students is 19 years. Correct answer is option (4).

    45 percent

Show Answer
Answer: ((d))

45 percent

Given:

Fail in Maths = 40%

Fail in English = 30%

Fail in both = 15%

Formula used:

Pass percentage = 100% - (Fail in Maths + Fail in English - Fail in both)

Calculation:

Pass percentage = 100% - (40 + 30 - 15)

⇒ Pass percentage = 100% - 55%

⇒ Pass percentage = 45%

∴ The correct answer is option (4).

Income and expenses for the years (in lakhs):

2016: Income = 125, Expenses = 75

2017: Income = 150, Expenses = 100

2018: Income = 140, Expenses = 80

2019: Income = 160, Expenses = 90

2020: Income = 180, Expenses = 120

Formula used:

Saving = Income - Expenses

Saving percentage = (Saving ÷ Income) × 100

Average Saving Percentage = (Sum of saving percentages ÷ Number of years)

Calculation:

2016: Saving = 125 - 75 = 50

Saving percentage = (50 ÷ 125) × 100 = 40%

2017: Saving = 150 - 100 = 50

Saving percentage = (50 ÷ 150) × 100 = 33.33%

2018: Saving = 140 - 80 = 60

Saving percentage = (60 ÷ 140) × 100 = 42.86%

2019: Saving = 160 - 90 = 70

Saving percentage = (70 ÷ 160) × 100 = 43.75%

2020: Saving = 180 - 120 = 60

Saving percentage = (60 ÷ 180) × 100 = 33.33%

Sum of saving percentages = 40 + 33.33 + 42.86 + 43.75 + 33.33 = 193.27

Average Saving Percentage = 193.27 ÷ 5

⇒ Average Saving Percentage = 38.65%

∴ The correct answer is option (1).

A dealer buys 20 Buses for 10 lakhs. Of these 20 Buses, 4 Buses are 30 seater's and rests are 20 seater's. At what price he should sell the 30 seater so that if he sells the 20 seater's at 78 \frac{7}{8} of the 30 seater's price, he makes a profit of 44% on this?

  1. ((a))

    0.7 lakh

  2. ((b))

    0.8 lakh

  3. ((c))

    0.9 lakh

  4. ((d))

    1.2 lakh

Show Answer
Answer: ((b))

0.8 lakh

Given:

Total cost of 20 Buses = ₹10 lakhs

4 Buses are 30 seater's

16 Buses are 20 seater's

Profit = 44%

Price of 20 seater = 78\frac{7}{8} of 30 seater's price

Formula used:

Total Selling Price = Cost Price × (1 + Profit Percentage)

Price of 20 seater = 78\frac{7}{8} × Price of 30 seater

Calculation:

Total Selling Price = ₹10 lakhs × (1 + 0.44)

⇒ Total Selling Price = ₹14.4 lakhs

Let price of 30 seater = ₹x

Price of 20 seater = 78\frac{7}{8} × ₹x = ₹0.875x

Total Selling Price:

⇒ 4 × ₹x + 16 × ₹0.875x = ₹14.4 lakhs

⇒ 4x + 14x = ₹14.4 lakhs

⇒ 18x = ₹14.4 lakhs

⇒ x = ₹0.8 lakhs

∴ The correct answer is option (2).

    162

  3. ((c))

    198

  4. ((d))

    128

Show Answer
Answer: ((b))

162

Given:

Number of students = 255

Percentage of boys = 6623%66\frac{2}{3}\% = 23\frac{2}{3}

Percentage of girls = 100%6623%100\% - 66\frac{2}{3}\% = 3313%33\frac{1}{3}\% = 13\frac{1}{3}

Average score of boys = Average score of girls + 3313%33\frac{1}{3}\%

Overall average score = 198

Formula used:

Total score = Average × Number of students

Let average score of girls = x

Average score of boys = x + 3313%33\frac{1}{3}\% = x + 13x\frac{1}{3}x

Total score = (Number of boys × Average of boys) + (Number of girls × Average of girls)

Calculation:

Number of boys = 23×255=170\frac{2}{3} \times 255 = 170

Number of girls = 13×255=85\frac{1}{3} \times 255 = 85

Total score = 170×(x+13x)+85×x170 \times (x + \frac{1}{3}x) + 85 \times x

⇒ Total score = 170×43x+85×x170 \times \frac{4}{3}x + 85 \times x

⇒ Total score = 6803x+85x\frac{680}{3}x + 85x

Overall average = Total score / Total students

198=6803x+85x255198 = \frac{\frac{680}{3}x + 85x}{255}

198×255=6803x+85x198 \times 255 = \frac{680}{3}x + 85x

50490=680x+255×85x350490 = \frac{680x + 255 \times 85x}{3}

50490×3=680x+255×85x50490 \times 3 = 680x + 255 \times 85x

151470=680x+21675x151470 = 680x + 21675x

151470=22355x151470 = 22355x

x=15147022355x = \frac{151470}{22355}

    Rs.28800

Show Answer
Answer: ((a))

Rs.22400

Given:

Income ratio (A : B) = 3 : 5

Savings of A = ₹3600

Savings of B = ₹5600

Expenditure of A = 5717100\frac{57\frac{1}{7}}{100} of Expenditure of B

Formula used:

Income = Savings + Expenditure

Expenditure of A = 5717100\frac{57\frac{1}{7}}{100} × Expenditure of B

Calculations:

5717100=400700=47\frac{57\frac{1}{7}}{100} = \frac{400}{700} = \frac{4}{7}

Let Expenditure of B = 7x

⇒ Expenditure of A = 4x

Income of A = Savings of A + Expenditure of A

⇒ Income of A = ₹3600 + 4x

Income of B = Savings of B + Expenditure of B

⇒ Income of B = ₹5600 + 7x

Given, Income ratio:

3600+4x5600+7x=35\frac{3600 + 4x}{5600 + 7x} = \frac{3}{5}

⇒ 5(3600 + 4x) = 3(5600 + 7x)

⇒ 18000 + 20x = 16800 + 21x

⇒ 18000 - 16800 = 21x - 20x

⇒ 1200 = x

Expenditure of B = 7x = ₹7 × 1200 = ₹8400

Expenditure of A = 4x = ₹4 × 1200 = ₹4800

Income of A = ₹3600 + ₹4800 = ₹8400

Income of B = ₹5600 + ₹8400 = ₹14000

Total income = ₹8400 + ₹14000 = ₹22400

∴ The correct answer is option (1).

Show Answer
Answer: ((b))

3313% 33\frac{1}{3}\%

Given:

Price increase = 12.5%

Revenue increase = 50%

Sale increase = x%

Formula used:

Revenue = Price × Quantity

If Price increases by a% and Revenue increases by b%, then:

New Quantity = (1 + b/100) / (1 + a/100)

Sale increase (x%) = (New Quantity - 1) × 100

Calculation:

New Quantity = (1 + 50/100) / (1 + 12.5/100)

⇒ New Quantity = (1.50) / (1.125)

⇒ New Quantity = 1.3333

Sale increase (x%) = (1.3333 - 1) × 100

⇒ x% = 0.3333 × 100

⇒ x = 33.33%

∴ The correct answer is option (2): 3313% 33\frac{1}{3}\%

Show Answer
Answer: ((a))

Rs.1785

Given:

Capital ratio of A : B : C = 34:45:56\frac{3}{4} : \frac{4}{5} : \frac{5}{6}

Total profit = ₹5110

B increases his capital by 25% after 9 months

Formula used:

Profit share = Capital invested × Time

Calculations:

LCM of denominators (4, 5, 6) = 60

Capital ratio = (34×60:45×60:56×60)(\frac{3}{4}×60 : \frac{4}{5}×60 : \frac{5}{6}×60)

⇒ Capital ratio = (45 : 48 : 50)

Time for A and C = 12 months

Time for B = 9 months with initial capital + 3 months with increased capital

Increased capital of B = 48 × 1.25 = 60

Adjusted time ratio = (45×12 : 48×9 + 60×3 : 50×12)

⇒ Adjusted time ratio = (540 : 576 : 600)

Total ratio = 540 + 576 + 600 = 1716

B's share = 5761716×5110\frac{576}{1716} × 5110

⇒ B's share = ₹1785

∴ The share of B in the profit is ₹1785.

Show Answer
Answer: ((b))

1021086

Given:

Ratio of capitals = 9 : 3 : 8

C's profit = ₹216594

Formula used:

Total profit = (C's profit × Total ratio) ÷ C's ratio

Calculation:

Capital changes every 4 months:

A's capital: 9 × (1 + 1/3 + 1/3 + 1/3) = 9 × (1 + 1) = 18

B's capital: 3 × (1 + 3 + 3 + 3) = 3 × 10 = 30

C's capital: 8 × (1 + 1/2 + 1/2 + 1/2) = 8 × (1 + 1.5) = 12

Total ratio = A + B + C = 18 + 30 + 12 = 60

⇒ Total profit = (216594 × 60) ÷ 12

⇒ Total profit = ₹1021086

∴ The correct answer is option (2).

Mr. Smith decides to sell both his cars. He sells the first car at a loss of 20%. He marks the second car up by 100% and then gives a discount of 40%. What is the loss or gain in the transaction, given that the selling prices of both the cars are the same?

  1. ((a))

    3% loss

  2. ((b))

    2% loss

  3. ((c))

    4% loss

  4. ((d))

    3% gain

Show Answer
Answer: ((c))

4% loss

Given:

Loss on the first car = 20%

Mark-up on the second car = 100%

Discount on the second car = 40%

Selling prices of both cars are the same.

Formula used:

Selling Price (SP) = Cost Price (CP) × (1 ± Loss% or Gain%)

Calculation:

Let the Cost Price (CP) of the first car = ₹100

Loss = 20%

⇒ SP of the first car = 100 × (1 - 20/100)

⇒ SP = ₹80

Let the Cost Price (CP) of the second car = ₹x

Mark-up = 100%

⇒ Marked Price (MP) = x × (1 + 100/100)

⇒ MP = ₹2x

Discount = 40%

⇒ SP of the second car = MP × (1 - 40/100)

⇒ SP = 2x × (1 - 40/100)

⇒ SP = 2x × 60/100

⇒ SP = ₹1.2x

Since SPs of both cars are the same:

⇒ 80 = 1.2x

⇒ x = 80/1.2

⇒ x = ₹66.67

Total CP = 100 + 66.67 = ₹166.67

Total SP = 80 + 80 = ₹160

Loss = Total CP - Total SP

⇒ Loss = 166.67 - 160

⇒ Loss = ₹6.67

Loss% = (Loss/Total CP) × 100

⇒ Loss% = (6.67/166.67) × 100

⇒ Loss% ≈ 4%

∴ The correct answer is option (3).

Let price of cheapest diamond = x

Price of 2 costliest diamonds = 2x

Calculation:

Total price = ₹10 crore × 3 = ₹30 crore

x + 2x = ₹30 crore

⇒ 3x = ₹30 crore

⇒ x = ₹10 crore ÷ 3

⇒ x = ₹10 crore ÷ 3 = ₹10 ÷ 3 = ₹3 crore

∴ The price of the cheapest diamond is ₹3 crore, hence the correct answer is option (1).

Given:

Speed of faster train = 64 km/hr

Speed of slower train = 54 km/hr

Time taken = 18 seconds

Formula used:

Relative speed = Speed of faster train - Speed of slower train

Distance = Relative speed × Time

Calculations:

Relative speed = (64 - 54) km/hr

⇒ Relative speed = 10 km/hr

⇒ Convert km/hr to m/s: 10 × (1000 ÷ 3600)

⇒ Relative speed = 25/9 m/s

Distance = Relative speed × Time

⇒ Distance = (25/9) × 18

⇒ Distance = 50 m

∴ Length of each train = 50 ÷ 2 = 25 m

∴ The correct answer is option (3).

  2. ((b))

    10 km

  3. ((c))

    18 km

  4. ((d))

    25 km

Show Answer
Answer: ((d))

25 km

Given:

Speed from A to B = 50 km/h

Speed from B to C = 30 km/h

Total distance (A to C) = 100 km

Total time = 9:30 am - 6:00 am = 3.5 hours

Halt at B = 0.5 hours

Formula used:

Distance = Speed × Time

Calculations:

Time for driving = Total time - Halt time = 3.5 - 0.5 = 3 hours

Let distance from A to B = x km

Distance from B to C = 100 - x km

Time from A to B = x/50

Time from B to C = (100 - x)/30

Total driving time = Time from A to B + Time from B to C

⇒ 3 = x/50 + (100 - x)/30

⇒ LCM = 150

⇒ 3 = (3x + 5(100 - x))/150

⇒ 450 = 3x + 500 - 5x

⇒ 450 = 500 - 2x

⇒ 2x = 500 - 450

⇒ x = 50/2

⇒ x = 25 km

∴ The correct answer is option (4).

A passenger train overtakes two girls who are walking in the opposite direction in which the train is going at the rate of 6 km/h and 12 km/h and passes them completely in 36 seconds and 30 seconds respectively. What is the length of the train (in metres)?

  1. ((a))

    120 m

  2. ((b))

    300 m

  3. ((c))

    140 m

  4. ((d))

    125 m

Show Answer
Answer: ((b))

300 m

Given:

Speed of train (vtrain) = ?

Speed of girl 1 (vgirl1) = 6 km/h

Speed of girl 2 (vgirl2) = 12 km/h

Time taken by train to pass girl 1 (t1) = 36 seconds

Time taken by train to pass girl 2 (t2) = 30 seconds

Formula used:

Distance (length of train) = Relative speed × Time

Relative speed = Speed of train + Speed of girl (since they are moving in opposite directions)

Calculations:

Relative speed for girl 1:

⇒ vrelative1 = vtrain + vgirl1

Relative speed for girl 2:

⇒ vrelative2 = vtrain + vgirl2

Using the formula for distance:

Length of train for girl 1:

⇒ Ltrain = vrelative1 × t1

Length of train for girl 2:

⇒ Ltrain = vrelative2 × t2

Convert km/h to m/s:

⇒ 1 km/h = 5/18 m/s

Speed of girl 1:

⇒ vgirl1 = 6 × 5/18 = 5/3 m/s

Speed of girl 2:

⇒ vgirl2 = 12 × 5/18 = 10/3 m/s

Relative speed for girl 1:

⇒ vrelative1 = vtrain + 5/3

Relative speed for girl 2:

⇒ vrelative2 = vtrain + 10/3

Using the time to pass:

For girl 1:

⇒ L = (vtrain + 5/3) × 36

For girl 2:

⇒ L = (vtrain + 10/3) × 30

Equating both lengths:

⇒ (vtrain + 5/3) × 36 = (vtrain + 10/3) × 30

⇒ 36vtrain + 60 = 30vtrain + 100

⇒ 6vtrain = 40

⇒ vtrain = 40/6 = 20/3 m/s

Now calculate the length:

For girl 1:

Show Answer
Answer: ((c))

Opposite to the flow of liquid

The correct answer is Opposite to the flow of liquid.

Key Points

  • Viscous force refers to the internal frictional force in a fluid that arises due to the relative motion of its layers. This force acts to resist the motion of one layer relative to another.
  • The direction of the viscous force is always opposite to the flow of liquid, as it acts as a resistive force attempting to slow down or stop the relative motion of the fluid layers.
  • For example, when a liquid flows over a surface, the layers of the liquid in contact with the surface move slower due to the viscous force acting in the opposite direction of the flow.
  • The magnitude of the viscous force depends on several factors, including the velocity gradient (rate of change of velocity between adjacent layers), the area of contact, and the viscosity of the fluid.
  • Viscous force is a key concept in fluid mechanics and plays a crucial role in determining the flow behavior of liquids in various applications, such as pipe flow, lubrication, and aerodynamics.

  • The unit of viscosity in the SI system is Pascal-second (Pa·s).
  • Newton's Law of Viscosity:
  • It states that the viscous force (F) between fluid layers is directly proportional to the velocity gradient (du/dy) and the area of contact (A).
  • The formula is given by: F = μ × A × (du/dy), where μ is the dynamic viscosity of the fluid.
  • Applications of Viscous Force:
  • In lubrication systems, viscous forces are crucial for reducing friction between moving parts in machinery.
  • In blood flow analysis, viscosity helps understand the flow of blood in arteries and veins.
  • In aerodynamics, viscous forces are considered in the design of aircraft to minimize drag.

  • When an injury occurs, platelets adhere to the damaged vessel wall and release various substances, including thromboplastin, which triggers the clotting cascade.
  • The clotting cascade involves several steps where clotting factors interact, ultimately leading to the formation of a fibrin clot to stop bleeding.
  • Other blood cells, such as monocytes, lymphocytes, and erythrocytes, do not produce or secrete thromboplastin. Their primary roles are immunity and oxygen transport, not clotting. Hence, these options are incorrect.
  • Therefore, platelets are responsible for the secretion of thromboplastin during the coagulation process.

Additional Information

  • Platelets:
  • Platelets are non-nucleated cell fragments derived from megakaryocytes in the bone marrow.
  • The normal platelet count in humans ranges from 150,000 to 450,000 per microliter of blood.
  • They play a crucial role in primary hemostasis by forming a platelet plug at the site of vessel injury.
  • Platelets also participate in secondary hemostasis by releasing thromboplastin and other substances that activate clotting factors.
  • Disorders related to platelets include thrombocytopenia (low platelet count) and thrombocytosis (high platelet count).
  • Thromboplastin:
  • Also known as tissue factor or factor III, thromboplastin is a protein involved in the initiation of the clotting cascade.
  • It is released by damaged tissues and platelets when a blood vessel is injured.
  • Thromboplastin combines with calcium ions and clotting factor VII to activate factor X in the extrinsic pathway of coagulation.
  • This activation is a critical step in converting prothrombin to thrombin, which subsequently converts fibrinogen to fibrin, forming a stable clot.
  • Clotting Cascade:
  • The clotting cascade includes two pathways: the intrinsic pathway (activated by trauma inside the blood vessel) and the extrinsic pathway (activated by external trauma).
  • Both pathways converge at the activation of factor X, leading to the common pathway and the formation of fibrin clot.
  • Key clotting factors include prothrombin (factor II), fibrinogen (factor I), and calcium ions.
  • Defects in the clotting cascade may lead to bleeding disorders like hemophilia.
  • Other Blood Cells:
  • Monocytes: These are large white blood cells involved in the immune response. They do not contribute to blood clotting.
  • Lymphocytes: Responsible for immunity (B cells and T cells), they play no role in thromboplastin secretion or clot formation.
  • Erythrocytes: Commonly known as red blood cells, their primary function is oxygen transport. They are not involved in coagulation.

Important Points

  • Platelet Activation: Platelets release substances like ADP, serotonin, and thromboxane A2, which further recruit more platelets to the site of injury.
  • Vitamin K: This vitamin is essential for the synthesis of clotting factors (II, VII, IX, X) in the liver.
  • Anticoagulants: Medications like heparin and warfarin inhibit clot formation by interfering with clotting factors.
  • Clinical Applications: Platelet function tests and coagulation studies are used to diagnose bleeding disorders and monitor anticoagulant therapy.
