SSC CHSL Tier-1 2024: Official Paper (Held On: 05 Jul, 2024 Shift 3) (Previous Year Paper)

The correct answer is Option 1)

Key Points

• In the second part of the given sentence, the verb form 'would' is incorrect.
• The sentence structure suggests a conditional relationship.
• In conditional sentences, the present simple tense is used in the 'if' clause and the future simple tense is used in the main clause.
• Example: If she exercises daily, she will remain energetic and fit forever.
• Therefore, the correct form should be 'will' instead of 'would'.

Hence, the correct statement is: If she exercises daily, she will remain energetic and fit forever.

Additional Information

• If the sentence is a conditional statement, the correct structure is important.
• Example: If it rains, we will stay indoors.
• Use the simple present tense in the 'if' clause and the simple future tense in the main clause for most real conditional statements.
• Example: If you study hard, you will pass the exam.

The correct answer is  Option 4)

Key Points

• In the first part of the given sentence, the article 'A' is incorrect.
• In the given sentence, the correct article should be 'An' because the noun 'owl' begins with a vowel sound.
• Thus, the correct form should be 'An owl is a bird, which has wide eyes, asymmetrical ears and is found mostly in forests.'

Hence, the correct statement is: An owl is a bird which has wide eyes, asymmetrical ears and is found mostly in forests.

<br>

Additional Information

• When a noun starts with a vowel sound, the article 'An' is used before it.
• Example: An apple a day keeps the doctor away.
• When a noun starts with a consonant sound, the article 'A' is used before it.
• Example: A cat is sitting on the wall.

The correct answer is Option 1)

Key Points

• In the given sentence, the phrase 'if you will' is incorrect.
• In conditional sentences, the simple present tense is used in the condition clause (after 'if').
• The correct construction should be 'if you come'.
• Example: If you come on time, the teacher will never give you punishment.

Hence, the correct statement is: The teacher will never give you punishment if you come on time.

<br>

Additional Information

• In conditional sentences, when the condition clause (if-clause) is in the simple present tense, the result clause (main clause) is usually in the simple future tense.
• Example: If it rains, we will stay indoors.
• Do not use the future tense in the if-clause.
• Incorrect: If you will come on time, we will start the meeting.
• Correct: If you come on time, we will start the meeting.

The correct answer is Option 3)

Key Points

• In the third part of the given sentence, the indefinite article 'a' is incorrect.
• The correct usage is the indefinite article 'an' before a word starting with a vowel sound like 'IPS'.
• Therefore, the correct form should be 'an IPS officer'.

Hence, the correct statement is: With hard work, commitment, and proper guidance, Sivaram has become an IPS officer.

<br>

Additional Information

• The indefinite article 'a' is used before words that begin with a consonant sound.
• The indefinite article 'an' is used before words that begin with a vowel sound.
• Examples:
• An apple in a day keeps the doctor away.
• A car is parked outside.

The correct answer is Option 2)

 

Key Points

• The context of the passage suggests a completed action or state, which requires the past participle form of the verb.
• "Characterised" fits well in the blank as it indicates something that has been described or distinguished by certain features.
• Other options like "characterising", "characteristic", and "characterises" do not fit the grammatical structure needed in the sentence.
• Hence, the correct word for fill in the blanks no. 1 is: Characterised.

Therefore, the correct answer is 'characterised'.

Additional Information

• Characterising: This form indicates an ongoing action, which does not fit the context.
• Characteristic: This form is a noun or adjective, not a verb, which is needed in the blank.
• Characterises: This present tense form does not fit the past context of the sentence.

The correct answer is Option 1)

 

Key Points

• The passage discusses various underlying ideas and patterns.
• The appropriate noun should indicate a central topic or subject matter being discussed.
• "Themes" fits well as it denotes the main ideas or topics covered, which aligns with the context.
• Other options ("problems", "arguments", "concerns") do not fit the context as well as "themes".
• Hence, the correct word fr fill in the blank no. 2 is: Themes.

Therefore, the correct answer is 'Option 1'.

 

 

Additional Information

• Problems (समस्याएं): "Problems" does not fit the context as well as "themes" since the passage is discussing central ideas rather than issues.
• Arguments (तर्क): "Arguments" does not reflect the central ideas or topics being discussed in the passage.
• Concerns (चिंताएं): "Concerns" does not align with the context of describing the main ideas or themes of the passage.

The correct answer is Option 2)

 

Key Points

• The passage discusses a past event or belief.
• The appropriate verb tense should indicate a past action or belief.
• "Believed" fits well as it denotes a past action, aligning with the context.
• Other options ("believes", "will believe", "could believe") do not fit the context of describing a past event or belief.
• Hence, the correct word for fill in the box no. 3 is 'believe.'

Therefore, the correct answer is 'Option 2'.

 

Additional Information

• Mercy (दयालुता): "Mercy" means compassion or forgiveness, which does not fit the context of discussing forest fire hazards.
• Trend (प्रवृत्ति): "Trend" means a general direction in which something is developing or changing, which does not reflect the idea of danger or harm.
• Failure (विफलता): "Failure" means lack of success, which does not align with describing the risk posed by forest fires.

The correct answer is Option 3)

 

Key Points

• The word "Another" is appropriate here because it introduces an additional aspect without repeating the same idea.
• The phrase "another important aspect" fits well in the context of listing multiple features of Romantic poetry.
• Other options like "Farther", "Additional," and "Mostly" do not fit as naturally in this sentence.
• Hence, the correct word for fill in the blanks no. 4 is 'another.'

Therefore, the correct answer is 'Option 3'.

Additional Information

• Farther (दूर): Generally used to indicate physical distance, which does not fit in the context of discussing an aspect of poetry.
• Additional (अतिरिक्त): Though close in meaning, it does not flow as naturally as "another" in this particular context.
• Mostly (अधिकतर): Indicates the majority of instances, which is not applicable to this context.

The correct answer is 'as well as'.

Key Points

• The passage discusses various characteristics and themes of Romantic poetry.
• The correct word should add another feature of Romantic poetry alongside personal expression and introspection.
• "As well as" (के साथ ही साथ) fits well as it adds another element (a rejection of traditional poetic forms and structures) that complements the focus on personal expression and introspection.
• Other options ("whereas", "therefore", "but") do not fit the context of adding additional information without implying a cause-and-effect relationship or contrast.

Therefore, the correct answer is 'Option 4'.

Additional Information

• Whereas (जबकि): "Whereas" is used to introduce a contrast.
• Therefore (अतः): "Therefore" is used to introduce a logical conclusion or result.
• But (लेकिन): "But" is used to introduce a contrast or exception.
• As well as (के साथ ही साथ): "As well as" is used to add another element or information in addition to what has already been mentioned.

The correct answer is Option 1)

 

Key Points

• The adjective "small" is appropriate because it directly contrasts with the adjective "big."
• The sentence compares the sizes of the bride's villa and the bridegroom's house, thus the size difference "small" is relevant.
• Options 2, 3, and 4 do not appropriately convey the comparative context based on size.

Therefore, the correct statemeent is: "The bride had a big villa in comparison to the bridegroom’s small house."

 

Additional Information

• Option 2: "different" is incorrect because the sentence focuses on size rather than distinction or type.
• Option 3: "distinct" is incorrect as it implies uniqueness rather than size difference.
• Option 4: "large" is incorrect; a large house would not explain a comparative size difference with the bride’s villa.

The correct answer is Option 1)

Key Points

• The word "objective" means not influenced by personal feelings or opinions in considering and representing facts. (वस्तुनिष्ठ)
• Example: The judge gave an objective assessment of the case based solely on the evidence presented.
• "Unbiased" means showing no prejudice for or against something; impartial. (निष्पक्ष)
• Example: The committee's decision was unbiased and based on merit.

Hence, we can infer that the correct substitution for 'objective' is 'unbiased'.

• The phrase "too close and big" correctly describes why planets in our solar system do not twinkle like stars.

Hence, the correct statement is: Planets in our solar system are too close and big for them to twinkle.

<br>

Additional Information

• The phrase "too close and big" indicates that the proximity and size of the planets prevent them from twinkling, which is a phenomenon typically observed in distant stars.
• Twinkling occurs due to atmospheric disturbances affecting the light from distant stars, but planets are close enough that their light doesn't get affected in the same way.

The correct answer is Option 1)

 

Key Points

• The adjective "nosy" is appropriate because it means inquisitive in an intrusive or prying manner, which fits the context of the sentence.
• The sentence describes Raju as someone who pries into other people's business, thus "nosy" has the correct connotation.
• Options 2, 3, and 4 do not appropriately convey the sense of prying.

Therefore, the correct sentece is: "Raju is such a nosy always prying into other people's business!"

 

Additional Information

• Option 2: "cheeky" is incorrect because it means impudently bold or disrespectful, which does not fit the context.
• Option 3: "perky" is incorrect; it means cheerful and lively, which is not relevant here.
• Option 4: "stingy" is incorrect as it implies unwillingness to spend money, which is unrelated to the context of being intrusive.

Decoding the Symbols:

So, Checking the options one by one

Option - (1): T – R + V ÷ S → T is the mother of R who is the brother of V who is the son of S.

Here, S is the husband of T.

Option - (2): T × R – V + S → T is the sister of R who is the mother of V who is the brother of S.

Here, S is either the nephew or niece of T.

Option - (3): T – R ÷ V × S → T is the mother of R who is the son of V who is the sister of S.

​

Here, S is either the brother-in-law or sister-in-law of T.

Option - (4): T ÷ R × V + S → T is the son of R who is the sister of V who is the brother of S.

Here, S is either the maternal aunt or maternal uncle of T.

Thus, out of all options 'T – R + V ÷ S' shows that S is the husband of T.

Hence, the correct answer is "Option - (1)".

The logic followed here is:

Logic: 1st number × 9 = 2nd number.

Now,

For, 14 : 126

⇒ 14 × 9 = 126.

For, 21 : 189

⇒ 21 × 9 = 189.

Similarly, for 32 ∶ ?

⇒ 32 × 9 = 288.

Hence, the correct answer is "Option 1".

Given Equation: 28 B 7 D 176 A 8 C 13 = ?

BODMAS Rule:

Decoding the given information:

 

Now replacing the sign from left to right using BODMAS Rule, we get:

⇒ 28 × 7 - 176 ÷ 8 + 13 = ?

⇒ 28 × 7 - 22 + 13 = ?

⇒ 196 - 22 + 13 = ?

⇒ 209 - 22 = 187.

Hence, the correct option is "Option 1".

Given : 136 − (176 ÷ 11) × 8 + 22 × 3 = 105

According to the question, after replacing the numbers :

Option - (1): 11 and 22

136 − (176 ÷ 11) × 8 + 22 × 3 = 105 ⇒ 136 − (176 ÷ 22) × 8 + 11 × 3 = 105

136 − (176 ÷ 22) × 8 + 11 × 3 = 105

136 − 8 × 8 + 11 × 3 = 105

136 + 33 - 64 = 105

169 - 64 = 105

105 = 105 (LHS = RHS)

Option - (2): 22 and 176

136 − (176 ÷ 11) × 8 + 22 × 3 = 105 ⇒ 136 − (22 ÷ 11) × 8 + 176 × 3 = 105

136 − (22 ÷ 11) × 8 + 176 × 3 = 105

136 − 2 × 8 + 176 × 3 = 105

136 + 528 - 16 = 105

664 - 16 = 105

648 ≠ 105 (LHS ≠ RHS)

Option - (3): 8 and 11

136 − (176 ÷ 11) × 8 + 22 × 3 = 105 ⇒ 136 − (176 ÷ 8) × 11 + 22 × 3 = 105

136 − (176 ÷ 8) × 11 + 22 × 3 = 105

136 - 22 × 11 + 22 × 3 = 105

136 + 66 - 242 = 105

202 - 242 = 105

-40 ≠ 105 (LHS ≠ RHS)

Option - (4): 8 and 3

136 − (176 ÷ 11) × 8 + 22 × 3 = 105 ⇒ 136 − (176 ÷ 11) × 3 + 22 × 8 = 105

136 − (176 ÷ 11) × 3 + 22 × 8 = 105

136 - 16 × 3 + 22 × 8 = 105

136 + 176 - 48 = 105

312 - 48 = 105

264 ≠ 105 (LHS ≠ RHS)

Hence, "Option - (1)" is the correct answer.

The logic followed here is: No specific pattern is followed here, random digits are assigned to each letter of the word.

‘AUDIO’ is coded as ‘59416’

And,

‘BEND’ is coded as ‘6238’

As 'D' is common, therefore it can be concluded that :

D is coded as → 6

So, the code for 'D' is '6'.

Hence, "Option - (4)" is the correct answer.

Logic: (5) is subtracted from the position values according to the English alphabetic series.

​​So,

ZBRL is related to UWMG

​ 

​And,

IDSQ is related to DYNL

​ 

​Similarly,

EVNA is related to

​

Hence, "Option - (2)" is the correct answer.

The least possible Venn diagram for the given statements is as shown below :

Conclusions:

I. No tiger is a cat → Does not follow (As some lions are panthers, no panther is a tiger and some lions are cats. As no direct relation is given between tiger and cat, therefore it is false.)

II. Some lions are tiger → Does not follow (As some lions are panthers and no panther is a tiger. So, It is possible but not definitely true)

III No cat is a panther → Does not follow (As some lions are panthers and some lions are cats. As no direct relation is given between tiger and cat, therefore it is false.)

∴ Here, Neither conclusions I, II nor III follow.​

Hence, the correct answer is "Neither conclusions I, II nor III follows"

Logic: (5), (2), and (4) are added to the first, second, and third letters position values according to the English alphabetic series respectively.

​​So,

​ 

Hence, "Option - (3)" is the correct answer.

The correct mirror image of the given figure is:

​​

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: Disability caused by the absence of a sensory function.

Here,

Light : Blind → Blind is a disability caused by the absence of light perception.

Similarly,

Speech : Dumb → Dumb is a disability caused by the absence of the ability to produce speech.

Hence, the correct answer is "Option 4".

Logic:

1. First and second letter → (1) is added to the position values according to the English alphabetic series.
   
2. Third letter → (1) is subtracted from the position values according to the English alphabetic series.

​​So,

​

Hence, "Option 4" is the correct answer.

Logic: ​

Option (1): PSU

Option (2): HKN

Option (3): DGJ

Option (4): TWZ

Thus, out of all the options "PSU" is the odd one out.

Hence, "Option 1" is the correct answer.

The faces opposite to each other are shown below:

⇒ As the alternate positions become opposite to each other, the remaining two faces become opposite to each other.

So, opposite pairs are:

Plum → Pear

Mango → Kiwi

Lime → Mango

Therefore, 'Mango' is the opposite of 'Kiwi'.

Hence, "Mango" is the correct answer.

The logic followed here is: No specific pattern is followed here, random digits are assigned to each letter of the word.

'RUIN' is coded as '3098'

And,

'TURN' is coded as '9630'

As, 'R', 'U', and 'N' are common, therefore it can be concluded that :

T is coded as → 6

I is coded as → 8

So, the code for 'I' is '8'.

Hence, "Option - (1)" is the correct answer.

Given : 35 × 96 - 8 + 3 ÷ 11 = ? 

According to the question, after replacing the signs :

‘+’ and ‘÷’ are interchanged 

‘×’ and ‘-’ are interchanged

So,​​

39 ÷ 13 - 12 + 5 × 4 = ? 

39 ÷ 13 - 12 + 5 × 4 = ?

3 - 12 + 5 × 4 = ?

3 + 20 - 12 = ?

23 - 12 = ?

11 = ?

Hence, "11" is the correct answer.

According to the given figure:

The figure will appear when it is opened as follows:

Hence, "Option - (3)" is the correct answer.

Given: 15 August 2006 was Tuesday.

Now,

2006 to 2017 = 11 Years (8 Ordinary Year and 3 Leap Year).

And, In 11 Years = 3 Leap years and 8 Ordinary Year.

So, 3 Leap Year has 6 odd days,

And, 8 Ordinary Year has 8 odd days.

Total odd days = 6 + 8 = 14.

14 odd days → 14/7 = 2 weeks and 0 odd days.

then, 15 August 2017 will be Tuesday + 0 = Tuesday.

Now, the number of days between 15 August 2017 to 7 September 2017

= 16(August) + 7(September) = 23 days.

= 23 days → 23/7 = 3 weeks and 2 odd days.

So, 7 September 2017 will be Tuesday + 2 = Thursday.

Hence, the correct answer is "Option 3".

Logic: Consecutive multiplies of (4) are added subsequently.

Hence, "83" is the correct answer.

The correct mirror image of the given figure is:

​​​

Hence, the correct answer is "Option 3".

The logic followed here is :

1. First box alternate series → Elements shift in the downward clockwise direction diagonally.

2. Second box alternate series → Elements shift in the anticlockwise direction at the corners and the center element is replaced by new element.

Thus, the final series is :

Hence, "Option - (2)" is the correct answer.

Logic: (5) and (4) are added to the first two and last two letter position values according to the English alphabetic series respectively.

​​So,

YZWT is related to DEAX

​ 

​And,

QROL is related to VWSP

​ 

​Similarly,

RSPM is related to

​ 

Hence, "Option - (4)" is the correct answer.

The number of triangles in the given figure is shown below :

Here, as marked there are a total of 15 triangles.

Hence, "15" is the correct answer.

Given : 13 ÷ 3 + 2 × 2 - 11 = ? 

According to the question, after replacing the signs :

‘+’ and ‘-’ are interchanged 

‘×’ and ‘÷’ are interchanged

<br>

So,​​

13 × 3 - 2 ÷ 2 + 11 = ? 

13 × 3 - 2 ÷ 2 + 11 = ?

13 × 3 - 1 + 11 = ?

39 + 11 - 1 = ?

50 - 1 = ?

49 = ?

Hence, "49" is the correct answer.

The logic followed here is:

Logic: 1st number × 3rd number = 2nd number.

Now,

For, (12, 132, 11)

⇒ (12 × 11) = 132.

For, (13, 104, 8)

⇒ (13 × 8) = 104.

Similarly, for (7, 105, 15)

⇒ 7 × 15 = 105.

Hence, the correct answer is "Option 3".

Given:

Initial side length of the cube = a

New side length of the cube = 3a

Formula Used:

Calculation:

Initial Surface Area = 6a²

New Surface Area = 6(3a)²

New Surface Area = 6 × 9a²

New Surface Area = 54a²

Percentage Increase = \(\frac{54a² - 6a²}{6a²} \times 100\)

Percentage Increase = \(\frac{48a²}{6a²} \times 100\)

Percentage Increase = 8 × 100

Percentage Increase = 800%

The percentage increase in surface area of the cube is 800%.

Shortcut Trick

Let the initial toffees with R be 8 units (denominator of 3/8).

Toffees given to S = 3 units.

Remaining toffees with R = 8 − 3 = 5 units.

Current toffees with S = 3 units.

According to the question: 5 = k% of 3 ⇒ 5 = (k/100) × 3 ⇒ k = 500/3.

∴ The correct answer is 500/3.

Alternate Method

Given:

Fraction of toffees given by R to S = 3/8

Current condition: R = k% of S

Let the total toffees with R initially be 8x.

⇒ Toffees given to S = 3/8 × 8x = 3x

⇒ Remaining toffees with R = 8x − 3x = 5x

⇒ Toffees currently with S = 3x

⇒ As per the question, R = (k / 100) × S

⇒ 5x = (k / 100) × 3x

⇒ 5 = 3k / 100

⇒ 3k = 500

⇒ k = 500/3

∴ The correct answer is 500/3.

Additional Information

Percentage Base Rule

When calculating x is k% of y, the value y (following the word 'of') is always the base or denominator: k = (x / y) × 100.

Fraction to Percentage

To convert any fraction a/b to a percentage, multiply the fraction by 100 and add the % symbol.

Ratio Relation

If R and S are in the ratio a : b, then R is (a/b) × 100 percent of S, and S is (b/a) × 100 percent of R.

Given:

Speed in the first hour = 90 km/hr

Speed in the next two hours = 120 km/hr

Formula Used:

Average speed = Total distance travelled / Total time

Calculation:

Distance travelled in the first hour = Speed × Time

Distance travelled in the first hour = 90 km/hr × 1 hr

Distance travelled in the first hour = 90 km

Distance travelled in the next two hours = Speed × Time

Distance travelled in the next two hours = 120 km/hr × 2 hr

Distance travelled in the next two hours = 240 km

Total distance travelled = Distance in the first hour + Distance in the next two hours

Total distance travelled = 90 km + 240 km

Total distance travelled = 330 km

Total time = 1 hr + 2 hr

Total time = 3 hr

Average speed = Total distance travelled / Total time

Average speed = 330 km / 3 hr

Average speed = 110 km/hr

The average speed of the rider is 110 km/hr.

Given:

Length (l) = 30 cm

Breadth (b) = 20 cm

Total surface area (TSA) = 2600 cm²

Formula Used:

Total Surface Area of a cuboid = 2(lb + bh + hl)

Calculation:

Using the formula for total surface area:

$TSA = 2(lb + bh + hl)$

Substitute the given values:

2600 = 2(30 × 20 + 20 × h + h × 30)

Simplify inside the parentheses:

2600 = 2(600 + 20h + 30h)

2600 = 2(600 + 50h)

2600 = 1200 + 100h

Subtract 1200 from both sides:

1400 = 100h

Divide by 100:

⇒ h = 14 cm

The height of the cuboid is 14 cm.

Shortcut Trick

In right-angled ΔBDC, ∠C = 90° − ∠EBD = 90° − 40° = 50°.

In ΔAEC, the exterior angle at vertex E is ∠AEB (which is x).

By the Exterior Angle Theorem, x = ∠EAC + ∠ACE.

⇒ x = 38° + 50° = 88°.

∴ The correct answer is 88.

Alternate Method

Given: BD ⊥ AC, ∠EAC = 38°, ∠EBD = 40°, and E lies on BC.

Formula Used: Sum of angles in a triangle = 180°; Exterior angle of a triangle = Sum of two opposite interior angles.

In ΔBDC, since BD ⊥ AC, ∠BDC = 90°.

⇒ ∠BCD + ∠CBD + ∠BDC = 180°

⇒ ∠BCD + 40° + 90° = 180°

⇒ ∠BCD = 180° − 130° = 50°

Now, consider ΔAEC. The angle ∠ACE is the same as ∠BCD.

⇒ ∠ACE = 50°

In ΔAEC, the sum of interior angles is 180°:

⇒ ∠EAC + ∠ACE + ∠AEC = 180°

⇒ 38° + 50° + ∠AEC = 180°

⇒ ∠AEC = 180° − 88° = 92°

Since B, E, C are collinear points on a straight line:

⇒ ∠AEB + ∠AEC = 180°

⇒ x + 92° = 180°

⇒ x = 180° − 92° = 88°

∴ The correct answer is 88.

Additional Information

The two banks that have disbursed the same sum of loan over all four years are:

Bank C and Bank D

Given:

Perimeter of the equilateral triangle = 24 cm.

Formula Used:

1. Side length of an equilateral triangle = Perimeter / 3
2. Area of an equilateral triangle = (√3 / 4) × side²

Calculation:

Side length of the equilateral triangle = 24 / 3

⇒ Side length = 8 cm

Area = (√3 / 4) × 8²

⇒ Area = (√3 / 4) × 64

⇒ Area = 16√3

Approximating √3 ≈ 1.732

Area ≈ 16 × 1.732

Area ≈ 27.712

Rounded off to the nearest two decimal places, Area ≈ 27.71 cm²

The area of the equilateral triangle is 27.71 cm².

Given:

If the angle of the sector with radius 7 cm is 120° 

Formula Used:

Length of sector = θ/360 × 2π r

Calculation:

 Length of sector = θ/360 × 2π r

⇒ (120/360) × 2 (22/7) 7

⇒ 44/3

∴ The length of the sector (in cm) is 44/3 cm.

Given:

Cost Price (CP) = Rs. 10,000

Selling Price (SP) = Rs. 12,000

Potential Selling Price = Rs. 13,000

Calculation:

Potential Profit = Potential Selling Price - Cost Price

Potential Profit = Rs. 13,000 - Rs. 10,000

Potential Profit = Rs. 3,000

Actual Profit = Selling Price - Cost Price

Actual Profit = Rs. 12,000 - Rs. 10,000

Actual Profit = Rs. 2,000

Loss = 3000 - 2000 = 1000 

In percentage = (1000/10000)× 100 

⇒ 10% loss

∴ The percentage loss that he incurs is 10%.

Given:

Radius of the circle = 25 cm.

Distance between the two chords = 27 cm.

Length of one chord = 48 cm.

Formula Used:

For a chord of length 2l at a distance d from the center in a circle of radius R :

$l = \sqrt{R^2 - d^2}$

Calculation:

Let the two chords be AB and CD with AB = 48 cm and CD = x cm.

Distance of AB from the center OM = $d_1$

Distance of CD from the center ON = $d_2$

Given, $d_1$ + $d_2$ = 27 cm

Half of AB = 24 cm

Half of CD = x/2 cm

Using the formula for chord length:

24 = $\sqrt{25^2 - d_1^2}$

x/2 = $\sqrt{25^2 - d_2^2}$

Solving for $d_1$ :

$24 = \sqrt{625 - d_1^2}$

Squaring both sides:

⇒ 24² = 625 - $d_1^2$

⇒ 576 = 625 - $d_1^2$

⇒ $d_1^2$ = 625 - 576

⇒ $d_1^2$ = 49

⇒ $d_1$ = 7 cm

Since $d_1$ + $d_2$ = 27 :

⇒ $d_2$ = 27 - 7

⇒ $d_2$ = 20 cm

Using $d_2$ to find x:

$x/2 = \sqrt{625 - 20^2}$

⇒ x/2 = $\sqrt{625 - 400}$

⇒ x/2 = √225

⇒ x/2 = 15

⇒ x = 30 cm

The length of the other chord is 30 cm.

Given:

Total number of voters = 2,40,000

Percentage of invalid votes = 3%

Percentage of valid votes in favour of the candidate = 60%

Formula Used:

Valid votes = Total votes - Invalid votes

Votes in favour of the candidate = (Valid votes) × (Percentage of valid votes in favour)

Calculation:

Total votes = 2,40,000

Invalid votes = 3% of 2,40,000

Invalid votes = 0.03 × 2,40,000

Invalid votes = 7,200

Valid votes = Total votes - Invalid votes

Valid votes = 2,40,000 - 7,200

Valid votes = 2,32,800

Votes in favour of the candidate = 60% of valid votes

Votes in favour of the candidate = 0.60 × 2,32,800

Votes in favour of the candidate = 1,39,680

The number of valid votes polled in favour of the candidate is 1,39,680.

Given:

radius of there sphere are 75cm, 60cm and 45 cm

Formula used:

Volume of sphere = 4/3 πr³

a³ + b³ + c³ = 1/2 (a + b + c)[(a - b)² + (b - c)² + (c - a)²] + 3abc

Calculation:

Volume of new sphere = Sum of volume of all three sphere

⇒ 4/3 πR³ = 4/3 π(75)³ + 4/3 π(60)³ + 4/3 π(45)³

⇒ 4/3 πR3 = 4/3 π [75³ + 60³ + 45³]

⇒ R³ = [753 + 603 + 453]

⇒ R3 = 1/2 × (75 + 60 + 45) [(75 - 60)² + (60 - 45)² + (45 - 75)²] + 3 × 75 × 60 × 45

⇒ R3 = 1/2 × 180 [15² + 15² + 30²] + 3 × 75 × 60 × 45

⇒ R3 = 90 × (225 + 225 + 900) + 3 × 75 × 60 × 45

⇒ R3 = 90 [1350 + 6750]

⇒ R3 = 90 × 8100

⇒ R3 = 90 × 90 × 90

⇒ R = 90 cm

Hence, the radius of the big sphere is 90 cm.

Given:

A retailer gets a discount of 40% on the printed price of an article. 

Calculation:

Let assume marked price of an article = 100

After 40% discount on the marked price,

Cost price for the retailer = 40% of Marked price

= 60% of 100

= 60

So, cost price = Rs. 60

Now the retailer is selling at the marked price,

So, profit of the retailer = $\dfrac{100-60}{60} \times 100$

= $\dfrac{40}{60} \times 100$

= $66 \frac{2}{3} \%$

So, the percentage of profit of the retailer is $66 \frac{2}{3} \%$.

Given:

Length of the first train = 550 metres.

Speed of the first train = 78 km/h.

Length of the second train = 350 metres.

Speed of the second train = 30 km/h.

Formula Used:

Time = Total distance / Relative speed

Calculation:

Convert speeds from km/h to m/s:

Speed of the first train = 78 × (1000/3600) = 21.67 m/s

Speed of the second train = 30 × (1000/3600) = 8.33 m/s

Since the trains are running in opposite directions, their relative speed is the sum of their speeds:

Relative speed = 21.67 + 8.33 = 30 m/s

Total distance to be covered = Length of the first train + Length of the second train

Total distance = 550 + 350 = 900 metres

Time = Total distance / Relative speed

⇒ Time = 900 / 30

⇒ Time = 30 seconds

The correct answer is option 4.

Calculation:

Total expenditure each Sushma and Preeti = (1800 + 5000 + 6000 + 7200 + 2500 + 7500)

⇒ 30000

Expenditure incurred on health by Sushma

⇒ 7500

Angle of health expenditure = (7500/30000) × 360

⇒ 90 

Expenditure incurred on health by Preeti

⇒ 20% of 30000

⇒ 6000

Angle of health expenditure

⇒ (6000/30000)× 360

⇒ 72

∴ The difference between the central angle corresponding to the expenditure incurred on Health by Sushma and Preeti = 90 - 72 

⇒ 18°

∴ The difference between the central angle corresponding to the expenditure incurred on Health by Sushma and Preeti is 18°

Calculation:

Given point (0, 0) and line 6x + 8y - 48 = 0

Here, A = 6, B = 8, C = -48, x₁ = 0, y₁ = 0

Substitute values into the formula:

$\text{Distance} = \frac{|6(0) + 8(0) - 48|}{\sqrt{6^2 + 8^2}}$

⇒ $\text{Distance} = \frac{|0 + 0 - 48|}{\sqrt{36 + 64}}$

⇒ $\text{Distance} = \frac{48}{\sqrt{100}}$

⇒ $\text{Distance} = \frac{48}{10}$

⇒ $\text{Distance} = 4.8 , \text{units}$

The perpendicular length from the origin to the line 6x + 8y - 48 = 0 is 4.8 units.

⇒ 240 + 300 = 540

⇒ 540 + 1250 = 1790

⇒ 1790 + 470 = 2260

⇒ 2260 + 320 = 2580 (in thousands)

Total number of computers manufactured by company C:

270 + 490 + 430 + 1180 + 550

⇒ 270 + 490 = 760

⇒ 760 + 430 = 1190

⇒ 1190 + 1180 = 2370

⇒ 2370 + 550 = 2920 (in thousands)

Difference =  2920 - 2580

⇒ 340

The difference between the number of computers manufactured by company A and C during the period from 2010 to 2014 is 340 thousand.

Calculation:

Company A: Growth = ((34 - 34) / 34) * 100

⇒ Growth = 0%

Company B: Growth = ((32 - 17) / 17) * 100

⇒ Growth ≈ 88.24%

Company C: Growth = ((12 - 9) / 9) * 100

⇒ Growth ≈ 33.33%

Company D: Growth = ((5 - 4) / 4) * 100

⇒ Growth = 25%

Company E: Growth = ((5 - 2) / 2) * 100

⇒ Growth = 150%

∴ Company E has the highest growth in percentage with 150%.
