SSC CHSL Tier-1 2024: Official Paper (Held On: 10 Jul, 2024 Shift 3) (Previous Year Paper)

The correct answer is Option 3)

Key Points

• The primary issue in the sentence is the incorrect usage of "Shall have" at the beginning of the question.
• In standard English, the correct form should be "Shall you have" or "Will you bring".
• The phrase "Shall have" is not typically used to form a question in this context.
• Thus, the error is located in part 3 of the sentence.
• Therefore, the correct answer is Option 3.

Correct Sentence: "Shall you bring your note-book tomorrow?"

Additional Information

• 1) "tomorrow" – This part of the sentence is correct and does not require any changes.
• 2) "your note-book" – This part of the sentence is correct and does not require any changes.
• 4) "you bring" – This part of the sentence is correct and does not require any changes.
• No error – This would be the correct option if there were no mistakes in the sentence, but there is an error in part 3.

The correct answer is Option 2)

Key Points

• The primary issue in the sentence is the use of the preposition "into" instead of "in".
• The correct phrase should be "I used to eat in the evening", ensuring grammatical correctness and clarity.
• Thus, the error is located in Option 2 of the sentence.

Correct Sentence: "I used to eat in the evening when my parents were on night shifts."

Additional Information

• Option 1: "when my parents" – This part of the sentence is grammatically correct and does not require any changes.
• Option 3: "in the evening" – This part of the sentence is grammatically correct and does not require any changes.
• Option 4: "were on night shifts" – This part of the sentence is grammatically correct and does not require any changes.
• No error – This would be the correct option if there were no mistakes in the sentence, but there is an error in Option 2.

The correct answer is Option 2)

Key Points

• The second option correctly uses the future tense by stating, "If you work hard in the same manner, you will soon achieve success."
• It properly combines the present simple tense "work" with the future simple tense "will achieve."
• This structure follows the first conditional format, which is used for real or possible situations in the future.
• Therefore, the correct answer is Option 2.

Correct Sentence: "If you work hard in the same manner, you will soon achieve success."

Additional Information

• Option 1: "If you had work hard in the same manner, you will soon achieve success." – This is incorrect because "had work" is not grammatically correct; it should be "had worked" for past perfect tense, but then it doesn't match with "will achieve."
• Option 3: "If you have work hard in the same manner, you will soon achieve success." – This is incorrect because "have work" is not correct; it should be "have worked," but the present perfect tense with "will achieve" is not the correct match in this conditional sentence structure.
• Option 4: "If you worked hard in the same manner, you will soon achieve success." – This is incorrect as it mixes past simple tense "worked" with future simple tense "will achieve," which typically demands a different conditional format (second conditional).

The correct answer is Option 1)

Key Points

• The primary issue in the sentence is the phrase "ran over" in part 3.
• The phrase "ran over" implies hitting someone with a vehicle, which is not the intended meaning here.
• A more appropriate phrase would be "ran into her schoolmate," which means meeting someone by chance.
• Thus, the error is located in part 3 of the sentence.
• Therefore, the correct answer is 3.

Correct Sentence: "Ganga was out shopping at the mall and ran into her schoolmate."

Additional Information

• 1: "Ganga was" – This part of the sentence is grammatically correct and does not require any changes.
• 2: "out shopping at the mall" – This part of the sentence is grammatically correct and does not require any changes.
• 3: "and ran over" – This part contains the error as explained above.
• No error – This would be the correct option if there were no mistakes in the sentence, but there is an error in part 3.

The correct answer is Option 1)

Key Points

• The context of the passage suggests the need to disconnect occasionally for our health, indicating that the word should relate directly to the concept being discussed.
• The pronoun "it" properly concludes the sentiment, suggesting that disconnecting is crucial.
• Therefore, the correct answer is Option 1.

Correct Sentence: "In today’s fast-paced and technology-driven world, it is crucial to disconnect occasionally for the sake of our health."

Additional Information

• Option 2: "these" – This is incorrect because "these" is a plural pronoun and does not fit the singular context of the necessity to disconnect.
• Option 3: "this" – This is incorrect because "this" would need a noun to follow, and the sentence structure does not support this format.
• Option 4: "that" – This is incorrect because "that" refers to something previously mentioned, and the sentence does not clearly provide such a reference.

The correct answer is Option 3)

Key Points

• The context of the passage suggests a continuous or unbroken exposure to screens and digital demands that can lead to negative effects like stress and anxiety.
• The word "constant" accurately describes continuous exposure.
• Therefore, the correct answer is Option 3.

Correct Sentence: "In today’s fast-paced and technology-driven world, it is crucial to disconnect occasionally for the sake of our health. Constant exposure to screens and the demands of the digital era can lead to stress, anxiety, and reduced well-being."

Additional Information

• Option 1: "Interrupted" – This is incorrect because "interrupted" suggests breaks or stops, which is not the intended meaning in this context.
• Option 2: "Redundant" – This is incorrect as "redundant" means unnecessary repetition, which does not fit the context of continuous exposure.
• Option 4: "Sporadic" – This is incorrect because "sporadic" indicates irregular or infrequent occurrences, which is the opposite of what the passage conveys.

The correct answer is Option 4)

Key Points

• The phrase "engage in activities" is a common and grammatically correct expression. It means to participate or become involved in activities.
• "Engage" is usually followed by the preposition "in" when referring to activities or events.
• Therefore, the correct answer is Option 4.

Correct Sentence: "Taking time to unplug and engage in activities that promote relaxation, such as spending time in nature..............."

Additional Information

• Option 1: "into" – This is incorrect because "engage into" is not a standard collocation in English.
• Option 2: "to" – This is incorrect because "engage to" is also not a standard collocation in English for this context.
• Option 3: "for" – This is incorrect because "engage for" does not fit the intended meaning and standard usage.

The correct answer is Option 3)

Key Points

• The verb "pursuing" fits well in this context, as it conveys the idea of actively engaging in or following activities that bring relaxation and enjoyment.
• "Pursuing hobbies" is a common collocation that means engaging in hobbies.

Therefore, the correct answer is Option 3.

Correct Sentence: "Taking time to unplug and engage in activities that promote relaxation, such as spending time in nature, pursuing hobbies, or simply enjoying quality time with loved ones....................."

Additional Information

• Option 1: "chasing" – This is incorrect because "chasing" implies actively pursuing something in a relentless manner, which does not fit the relaxing and leisurely context of the sentence.
• Option 2: "constructing" – This is incorrect because "constructing" means building or creating something, which does not fit the context of engaging in hobbies for relaxation.
• Option 4: "trailing" – This is incorrect because "trailing" means following behind, which does not fit the context of engaging in relaxing activities.

The correct answer is Option 4)

Key Points

• The word "prioritise" fits well in this context as it conveys the action of giving more importance or precedence to mental and physical health.
• "Prioritise our mental and physical health" aligns with the intent of the passage to emphasize the importance of well-being.
• Therefore, the correct answer is Option 4.

Correct Sentence: "In today’s fast-paced and technology-driven world, it is crucial to disconnect occasionally for the sake of our health. Constant exposure to screens and the demands of the digital era can lead to stress, anxiety, and reduced well-being. Taking time to unplug and engage in activities that promote relaxation, such as spending time in nature, pursuing hobbies, or simply enjoying quality time with loved ones allows us to recharge, find balance, and prioritise our mental and physical health."

Additional Information

• Option 1: "precede" – This is incorrect because "precede" means to come before something, which does not fit the context of emphasizing health.
• Option 2: "underscore" – This is incorrect because "underscore" means to emphasize, which is similar to the intended meaning but does not quite fit in this context as naturally as "prioritise."
• Option 3: "focus" – This is incorrect because "focus" can imply paying attention to, but it misses the nuance of giving priority to health over other aspects.

The correct answer is Option 1)

• The term "blurred" is the most appropriate word to describe vision that is affected by an illness. It accurately conveys the idea of unclear or indistinct vision, which is a common symptom of various illnesses.
• The other options, such as "obscured," "unfocused," and "faded," do not precisely capture the typical way of describing vision problems due to illness.
• "Blurred vision" is a commonly used medical term that specifically refers to the loss of sharpness of vision and the inability to see fine details.
• Therefore, the correct answer is Option 1.

Correct Sentence: "He has blurred vision because of his illness."

Additional Information

• Option 2: "obscured" – This word suggests that something is blocking the vision, but it doesn't specifically describe the quality of the vision itself.
• Option 3: "unfocused" – This term implies that the vision is not sharp, but it is less commonly used in the context of vision problems due to illness.
• Option 4: "faded" – This word suggests a loss of color or brightness, which is not typically how vision problems are described.

First number = x + 30% of x

⇒ First number = x + 0.30x

⇒ First number = 1.30x

Second number = x + 40% of x

⇒ Second number = x + 0.40x

⇒ Second number = 1.40x

Ratio of second number to first number:

⇒ (1.40x) / (1.30x)

⇒ 1.40 / 1.30

⇒ 14 / 13

Hence, the ratio of the second number to the first number is 14 ∶ 13.

∴ The correct answer is option 4.

Let ∠DBP = ∠PBC = a°

And also ∠ECP + ∠PCB = b°

∠ABC = 180° - 2a° and ∠ACB = 180° - 2b°

In ΔABC,

180° - 2a° + 72° + 180° - 2b° = 180°

a° + b° = 126°

In ΔPBC,

a° + b° + x° = 180°

x° = 180° - 126° = 54°

∠BPC = 90° - (1/2) × ∠A

Here, ∠A = 72° 

∴ ∠BPC = 90° - (1/2) × 72° 

⇒ ∠BPC = 90° - 36° = 54°

Given:

Due to decrease in manpower, the production in a factory decreases by 25%.

We need to find by what percent the working hours should be increased to restore the original production.

Concept:

To restore the original production, the product of manpower and working hours should remain constant.

Formula Used:

Let the original working hours be H and the increased working hours be H'.

Let the original production be P and the decreased production be 0.75P (since it decreased by 25%).

To restore the original production:

P = 0.75P × (H'/H)

Calculation:

We have,

⇒ 1 = 0.75 × (H'/H)

⇒ H'/H = 1/0.75

⇒ H'/H = 4/3

⇒ H' = 4H/3

Percentage increase in working hours:

⇒ [(4H/3) - H]/H × 100%

⇒ (4H - 3H)/(3H) × 100%

⇒ H/(3H) × 100%

⇒ 1/3 × 100

⇒ 33 (1/3)%

∴ The correct answer is option 1.

Calculation:

The number of commercial vehicles sold in 2012 = 0.8

The total number of vehicles sold in 2011 = 14.98

⇒ (0.8/14.98)× 100

⇒ 5.34%

∴ The number of commercial vehicles sold in 2012 was approximately what percentage of the total number of vehicles sold in 2011 is 5.34%

Shortcut Trick The given equation is 4 sin2 θ − 4√3 sin θ + 3 = 0. This is in the form of (a − b)2 = a2 − 2ab + b2. Here, (2 sin θ)2 − 2(2 sin θ)(√3) + (√3)2 = 0. ⇒ (2 sin θ − √3)2 = 0 ⇒ 2 sin θ = √3 ⇒ sin θ = √3/2. Since sin 60° = √3/2, the value of θ is 60°. ∴ The correct answer is 60°. Alternate Method Given: 4 sin2 θ − 4√3 sin θ + 3 = 0, where 0 < θ < 90°. Formula Used: Quadratic formula x = [−b ± √(b2 − 4ac)] / 2a or factorization. Calculations: Let sin θ = x. Then the equation becomes: ⇒ 4x2 − 4√3x + 3 = 0 ⇒ 4x2 − 2√3x − 2√3x + 3 = 0 ⇒ 2x(2x − √3) − √3(2x − √3) = 0 ⇒ (2x − √3)(2x − √3) = 0 ⇒ (2x − √3)2 = 0 ⇒ 2x = √3 ⇒ x = √3/2 ⇒ sin θ = √3/2 ⇒ θ = sin−1(√3/2) ⇒ θ = 60° ∴ The correct answer is 60°. Additional Information Trigonometric Ratios of Standard Angles Values of sin θ for standard angles: sin 0° = 0, sin 30° = 1/2, sin 45° = 1/√2, sin 60° = √3/2, sin 90° = 1. Nature of Roots in Quadratic Equations For ax2 + bx + c = 0, the discriminant D = b2 − 4ac determines the nature. If D = 0, roots are real and equal.

⇒ 336 + 154

⇒ 490

The number of boy students of Physics and Biology = 450 × 70% + 200 × 20%

⇒ 315 + 40

⇒ 355

According to the question,

⇒ 490 : 355

⇒ 98 : 71

∴ The ratio of girl students of Mathematics and Chemistry to the number of boy students of Physics and Biology is 98 : 71.

Given:

Article size: 9 cm × 6 cm × 3 cm

Box size: 63 cm × 42 cm × 21 cm

Concept:

To find the number of articles that can fit into the box, we need to calculate the volume of both the article and the box. Then, we will divide the volume of the box by the volume of one article. Additionally, we need to ensure that the dimensions align correctly.

Formula Used:

Volume of a cuboid = length × width × height

Calculation:

Volume of one article:

⇒ 9 cm × 6 cm × 3 cm = 162 cm³

Volume of the box:

⇒ 63 cm × 42 cm × 21 cm = 55,566 cm³

Number of articles that can fit into the box:

⇒ 55,566 cm³ / 162 cm³

⇒ 343 articles

∴ The correct answer is option 2.

Given:

In a ΔPQR, RS intersects PQ at point S.

QR = 36 cm

SQ = 27 cm

RS = 18 cm

∠QRS = ∠QPR

Calculation:

In triangle PQR and QSR

∠QRS = ∠QPR (Given)

∠Q = ∠Q (Common)

So by AA rule, Δ PQR ∼ ΔQSR,

27/36 = 18/PR

PR = 24 cm

So, (27 + PS) / 36 = 36 / 27

PS = 48 - 27

PS = 21 cm

So, the ratio of the perimeter of ∆PRS to that of ∆QSR:

∆PRS / ∆QSR = (24 + 18 + 21) / (27 + 18 + 36) 

= 63 / 81

= $\frac{7}{9}$

Shortcut Trick

To get 8 identical pieces from 3 cuts, one cut must be made along each dimension (length, width, and height).

Each cut creates 2 additional surfaces equal to the area of the face it is parallel to.

Total added area ⇒ 2(20×12) + 2(12×10) + 2(10×20) ⇒ 480 + 240 + 400 = 1120 cm².

Original TSA of cuboid = 2(240 + 120 + 200) = 1120 cm².

Total Surface Area = Original Area + Added Area = 1120 + 1120 = 2240 cm².

∴ The correct answer is 2240 cm².

Alternate Method

Given: Length (L) = 20 cm, Width (W) = 12 cm, Height (H) = 10 cm.

Formula: Total Surface Area (TSA) of a cuboid = 2(LW + WH + LH).

⇒ Original TSA of the cuboid = 2 × (20 × 12 + 12 × 10 + 20 × 10)

⇒ Original TSA = 2 × (240 + 120 + 200) = 2 × 560 = 1120 cm².

⇒ For 8 identical pieces, dimensions of each small piece = (20/2) × (12/2) × (10/2) = 10 cm × 6 cm × 5 cm.

⇒ TSA of one small piece = 2 × (10 × 6 + 6 × 5 + 10 × 5)

⇒ TSA of one small piece = 2 × (60 + 30 + 50) = 2 × 140 = 280 cm².

⇒ Total TSA of 8 such pieces = 8 × 280 = 2240 cm².

∴ The correct answer is 2240 cm².

Additional Information

Surface Area Added by Cuts

Each cut in a solid object increases the total surface area by twice the area of the cross-section created by that cut.

Maximum Pieces from N Cuts

To maximize pieces, distribute cuts as equally as possible among the three axes. Total pieces = (x+1)(y+1)(z+1) where x+y+z = N.

Volume of Cuboid

The total volume remains constant after cutting: Volume = L × W × H.

Calculation:

[33{(40 × 5) + (7 × 6)} ÷ 11] + (23 × 15 ÷ 24)]

⇒ [33{200 + 42} ÷ 11] + 5]

⇒ [27 × 22 + 5]

⇒ 594 + 5

⇒ 599

∴ The value of [33{(40 × 5) + (7 × 6)} ÷ 11] + (23 × 15 ÷ 24)] is 599.

Given:

Reena and Riya together can complete a piece of work in 36 days.

Riya and Geeta together can complete it in 54 days

Reena and Geeta together can complete it in 81 days

Calculation:

Reena and Riya = 36 

Riya and Geeta = 54

Reena and Geeta = 81

Total Work LCM (36, 54, 81) = 324

Efficiency of Reena and Riya = 9

Efficiency of Riya and Geeta = 6

Efficiency of Reena and Geeta = 4

Efficiency of Reena + Riya + Geeta = 19/2

Efficiency of Reena = 19/2 - 6

⇒ 7/2

According to the question,

⇒ 324/(7/2)

⇒ 648/7

∴ Reena alone complete the work in $92 \frac{4}{7}$ days.

Given:

The student spent 16 hours per day distributed across five subjects. The percentage distribution of time and marks obtained in each subject is provided:

Hardwork in Time:

Math = 40%, Science = 20%, Economics = 10%, Sociology = 25%, English = 5%.

Marks Obtained:

Math = 21%, Science = 18%, Economics = 19%, Sociology = 22%, English = 20%.

Formula used:

The ratio of marks to time for each subject is calculated as:

$\frac{\text{Marks Obtained}}{\text{Time Spent}}$

Calculation:

For each subject:

 $\frac{\text{Math}}{Time} = \frac{21}{40} = 0.525$

$\frac{\text{Science}}{Time} = \frac{18}{20} = 0.9$

$\frac{\text{Economics}}{Time} = \frac{19}{10} = 1.9$

$\frac{\text{Sociology}}{Time} = \frac{22}{25} = 0.88$

$\frac{\text{English}}{Time} = \frac{20}{5} = 4$

⇒ The highest ratio is for English.

∴ The correct answer is option (4).

Given:

Ratios: 1 ∶ 5, 7 ∶ 4, 2 ∶ 3, 8 ∶ 3

Concept:

To compare the ratios, we convert each ratio to a decimal by dividing the first number by the second number.

Calculation:

We have,

⇒ 1 ∶ 5 = 1 ÷ 5 = 0.2

⇒ 7 ∶ 4 = 7 ÷ 4 = 1.75

⇒ 2 ∶ 3 = 2 ÷ 3 = 0.6667

⇒ 8 ∶ 3 = 8 ÷ 3 = 2.6667

Comparing the decimal values, we find:

0.2, 1.75, 0.6667, 2.6667

Hence, the greatest ratio is 8 ∶ 3.

∴ The correct answer is option 4.

Calculation:

The average sales of branches P1, P3 and P5 in 2016

⇒ (120 + 110 + 96)/3

⇒ 108.66

The average sales of branches P1, P2, P3 and P4 in 2015

⇒ (85 + 78 + 100 + 90)/4

⇒ 88.25

According to the question, 

⇒ (88.25/108.66)× 100

⇒ 81.21%

∴ The required answer is 81.21%.

Shortcut Trick

Number of Sundays in a 30-day month starting with Sunday = 5 (1^st, 8^th, 15^th, 22^nd, 29^th).

Remaining days = 30 − 5 = 25 days.

Using deviation method: Assume base average = 230.

Extra attendance on 5 Sundays = 5 × (410 − 230) = 5 × 180 = 900.

Net increase in average = 900 ÷ 30 = 30.

Average attendance = 230 + 30 = 260.

∴ The correct answer is 260.

Alternate Method

Given:

Average attendance on Sundays = 410

Average attendance on other days = 230

Total days in the month = 30 (Starts with Sunday)

Formula Used:

Average = (Total sum of attendance) ÷ (Total number of days)

Calculations:

⇒ Total attendance on Sundays = 5 × 410 = 2050

⇒ Total attendance on other days = (30 − 5) × 230 = 25 × 230 = 5750

⇒ Total attendance for 30 days = 2050 + 5750 = 7800

⇒ Average attendance per day = 7800 ÷ 30

⇒ Average attendance per day = 260

∴ The correct answer is 260.

Additional Information

Weighted Average Formula

When a group is divided into two parts with counts n₁, n₂ and averages a₁, a₂, the combined average is (n₁a₁ + n₂a₂) / (n₁ + n₂).

Occurrence of Days in a Month

In a month of 30 days, any day that falls on the 1^st or 2^nd will occur 5 times; all other days will occur 4 times.

Deviation Method for Averages

New Average = Old Average + (Total Deviation / Total Number of terms). This is useful for large numbers to simplify multiplication.

Given:

Let ABCD be a quadrilateral and AC, BD be diagonals.

The length of BD = 20 cm and the heights of the triangles ABD and BCD are, respectively, 6 cm, 8 cm.

Calculation:

According to the question,

Area of Quadrilateral = Sum of Area (Triangle ABD + Triangle BCD)

⇒ (1/2)× 20 × 6 + (1/2)× 20 × 8

⇒ 60 + 80 

⇒ 140

∴ The area of the quadrilateral ABCD is 140 cm².

Given:

Chords AB and CD of a circle, when produced, meet at a point P outside the circle. If AB = 6 cm, CD = 3 cm and PD = 5 cm

Calculation:

PA × PB = PC × PD

(6 + x) x = 8 × 5

⇒ x² + 6x - 40 = 0

⇒ x² + 10x - 4x - 40

⇒ (x + 10) (x - 4) = 0

⇒ x = 4

∴ PB is equal to 4 cm.

Shortcut Trick

When distance is constant, speed and time are inversely proportional.

Ratio of Time = 16 : 12 = 4 : 3 ⇒ Ratio of Speed = 3 : 4

Difference in speed ratio (1 unit) = 20 km/h

Original speed = 3 units = 60 km/h

Total distance = 60 km/h × 16 h = 960 km

∴ The correct answer is 960 km.

Alternate Method

Given:

Time taken at original speed = 16 hours

Time taken at increased speed = 12 hours

Increase in speed = 20 km/h

Formula Used:

Distance = Speed × Time

Distance = D Scenario 1: Speed = S km/h Time = 16 h

Distance = D Scenario 2: Speed = S + 20 km/h Time = 12 h

Distance is constant: S × 16 = (S + 20) × 12

Calculations:

Let the original speed be S km/h.

Since the distance covered in both cases is the same:

⇒ Distance₁ = Distance₂

⇒ S × 16 = (S + 20) × 12

⇒ 16S = 12S + 240

⇒ 16S − 12S = 240

⇒ 4S = 240

⇒ S = 60 km/h

Now, calculate the total distance covered by the car:

⇒ Distance = Speed × Time

⇒ Distance = 60 × 16 = 960 km

∴ The correct answer is 960 km.

Additional Information

Proportionality in Speed, Time, and Distance

If Distance is constant, Speed ∝ 1 / Time. If Time is constant, Distance ∝ Speed. If Speed is constant, Distance ∝ Time.

Average Speed

Average Speed = Total Distance ÷ Total Time. For equal distances covered at speeds x and y, Average Speed = (2xy) ÷ (x + y).

Relative Speed

When two objects move in the same direction, relative speed = |S₁ − S₂|. In opposite directions, relative speed = S₁ + S₂.

Given:

Marked price of the coat = Rs. 145

Offered price of the coat = Rs. 127.6

Concept:

The rate of retail discount is calculated using the formula:

Discount Rate (%) = [(Marked Price - Offered Price) / Marked Price] × 100

Calculation:

We have,

⇒ Marked Price = Rs. 145

⇒ Offered Price = Rs. 127.6

Using the formula,

⇒ Discount Rate (%) = [(145 - 127.6) / 145] × 100

⇒ Discount Rate (%) = [17.4 / 145] × 100

⇒ Discount Rate (%) = 0.12 × 100

⇒ Discount Rate (%) = 12%

∴ The correct answer is option 1.

Given:

42 ÷ 3 + k × 3 – 22 ÷ 11 + 4 = 28

Concept:

To find the value of k, we need to solve the equation by performing the arithmetic operations step-by-step.

Calculation:

We have,

⇒ 42 ÷ 3 + k × 3 – 22 ÷ 11 + 4 = 28

First, perform the division operations:

⇒ 14 + k × 3 – 2 + 4 = 28

Next, simplify the constants:

⇒ 14 – 2 + 4 = 16

⇒ 16 + k × 3 = 28

Isolate the term with k:

⇒ k × 3 = 28 – 16

⇒ k × 3 = 12

Solve for k:

⇒ k = 12 ÷ 3

⇒ k = 4

∴ The value of k is 4.

Given:

Cost of 21 pencils and 9 pens = Rs. 276

Cost of 6 pencils and 3 pens = Rs. 84

Concept:

We need to form and solve a system of linear equations to find the individual cost of one pencil and one pen.

Calculation:

Let the cost of one pencil be x and the cost of one pen be y.

We have the equations:

⇒ 21x + 9y = 276      ...(1)

⇒ 6x + 3y = 84      ...(2)

Divide equation (2) by 3:

⇒ 2x + y = 28      ...(3)

Multiply equation (3) by 9:

⇒ 18x + 9y = 252      ...(4)

Subtract equation (4) from equation (1):

⇒ (21x + 9y) - (18x + 9y) = 276 - 252

⇒ 3x = 24

⇒ x = 8

Substitute x = 8 into equation (3):

⇒ 2(8) + y = 28

⇒ 16 + y = 28

⇒ y = 12

Hence, the cost of one pencil and one pen is:

⇒ x + y = 8 + 12

⇒ x + y = 20

∴ The cost of one pencil and one pen is Rs. 20.

Given:

Merchant sells 195 kg of wheat for Rs. 10,260 with a profit of Rs. 4.50 per kg.

Concept:

The cost price (CP) can be calculated by subtracting the total profit from the selling price (SP).

Formula Used:

Total Profit = Profit per kg × Total kg

Cost Price (CP) = Selling Price (SP) - Total Profit

CP per kg = Total CP / Total kg

Calculation:

We have,

⇒ Total kg = 195 kg

⇒ Selling Price (SP) = Rs. 10,260

⇒ Profit per kg = Rs. 4.50

⇒ Total Profit = 195 kg × Rs. 4.50

⇒ Total Profit = Rs. 877.50

⇒ Cost Price (CP) = Rs. 10,260 - Rs. 877.50

⇒ CP = Rs. 9,382.50

⇒ CP per kg = Rs. 9,382.50 / 195 kg

⇒ CP per kg = Rs. 48.10 (approx.)

Cost Price of 15 kg of wheat:

⇒ 15 kg × Rs. 48.10

⇒ Rs. 721.50

To the nearest integer, Cost Price of 15 kg of wheat is Rs. 722.

∴ The correct answer is option 1.

Calculation:

r1 = 32 cm and r2 = 20 cm and the distance between the centers = D = 60 cm.

Length of direct common tangent = √(602 – (32 – 20)2) = √3456

Length of transverse common tangent = √(602 – (32 + 20)2) = √896

Required Ratio = √3456 : √896 

divide the number by √128

⇒ 3√3 : √7  

∴ The ratio of the length of the direct common tangent to the length of the transverse common tangent to these circles is 3√3 : √7.

Given:

A certain sum of money amounts to Rs. 1,860 in 2 years and to Rs. 2,130 in 3¹⁄₂ years at simple interest.

Concept:

Simple Interest (SI) is calculated using the formula:

SI = Principal (P) × Rate (R) × Time (T) / 100

Amount (A) is given by:

A = Principal (P) + Simple Interest (SI)

Calculation:

Let the principal be P and the rate of interest be R%.

For the first condition:

⇒ A₁ = P + (P × R × 2 / 100) = 1860

⇒ P (1 + 2R / 100) = 1860     ...(i)

For the second condition:

⇒ A₂ = P + (P × R × 3.5 / 100) = 2130

⇒ P (1 + 3.5R / 100) = 2130     ...(ii)

From equation (i):

⇒ P (1 + 2R / 100) = 1860

⇒ P = 1860 / (1 + 2R / 100)     ...(iii)

Substitute P from equation (iii) into equation (ii):

⇒ (1860 / (1 + 2R / 100)) × (1 + 3.5R / 100) = 2130

⇒ 1860 (1 + 3.5R / 100) = 2130 (1 + 2R / 100)

⇒ 1860 + 1860 × 3.5R / 100 = 2130 + 2130 × 2R / 100

⇒ 1860 + 65.1R = 2130 + 42.6R

⇒ 22.5R = 270

⇒ R = 270 / 22.5

⇒ R = 12%

Substitute R = 12% back into equation (iii) to find P:

⇒ P = 1860 / (1 + 2 × 12 / 100)

⇒ P = 1860 / 1.24

⇒ P = 1500

∴ The sum is Rs. 1,500 and the rate of interest is 12%.

Given:

Candidate A secures 40% of the votes.

Candidate B secures the remaining votes, which is 60%.

Majority by Candidate B = 298 votes.

Calculations:

Let the total number of votes be V.

Votes secured by Candidate A = 0.40V.

Votes secured by Candidate B = 0.60V.

According to the problem, the difference in votes is:

Votes of Candidate B - Votes of Candidate A = 298.

Substituting the values gives:

0.60V - 0.40V = 298.

0.20V = 298.

Now solving for V:

V = 298 / 0.20 = 1490.

∴ The total number of votes recorded is 1490.
