SSC CHSL 2025 Tier-1 (Held On: 19 Nov, 2025 Shift 2) (Previous Year Paper)

The correct answer is '2' i.e. was you .

Key Points

• The sentence "If I was you, I wouldn't do this" is grammatically incorrect. This is because it uses the incorrect form of the verb "was" in the conditional clause.
• The sentence is an example of the second conditional, which is used to express hypothetical or unreal situations.
• In the second conditional, the correct structure is "If + subject + were, subject + would + base verb."
• The word "was" should be replaced with "were," as the phrase "If I were" is used to indicate hypothetical situations, regardless of the subject.

Correct sentence: If I were you, I wouldn't do this.

Additional Information

• 1st Conditional Sentence:
• Structure: If + Present Simple, will + base verb.
• Example: If it rains, we will cancel the picnic.
• Usage: Describes real or possible situations in the future with likely outcomes.
• 2nd Conditional Sentence:
• Structure: If + Past Simple, would + base verb.
• Example: If I were rich, I would buy a mansion.
• Usage: Describes hypothetical or unreal situations in the present or future.
• 3rd Conditional Sentence:
• Structure: If + Past Perfect, would have + past participle.
• Example: If she had studied harder, she would have passed the exam.
• Usage: Refers to unreal past situations and their imagined outcomes.

The correct answer is '2' i.e. to attend .

Key Points

• The verb “deny” is not followed by the infinitive “to + base verb”. Instead, it is followed by a gerund (verb + ing).
• In this case, the correct form should be “denied attending”, not “denied to attend.”
• Therefore, the error lies in the phrase “to attend.”

Correct sentence: He denied attending the meeting citing personal reasons.

Additional Information

• Usage of “deny”:
• When using the verb “deny,” always follow it with a gerund (verb + ing).
• Example: She denied stealing the money.
• Common Verbs Followed by Gerunds:
• Enjoy, avoid, suggest, finish, deny, mind, etc.
• Example: He enjoys swimming. / She suggested going out for dinner.

The correct answer is '1' i.e. addressed .

Key Points

• The sentence is in the past tense, as indicated by the phrase "After months of silence."
• The context suggests that the author took an action regarding the controversy, which aligns with the meaning of "addressed."
• The word "addressed" means to deal with or focus on a specific issue, making it the most appropriate choice for the sentence.
• Other options are incorrect as they don’t fit the context:
• Suppressed: Means to hide or restrain, which doesn’t match the context of discussing the controversy.
• Diverted: Means to shift focus away from something, which is the opposite of what the sentence implies.
• Evaded: Means to avoid, which doesn’t align with the author finally confronting the issue.

Correct sentence: After months of silence, the author finally addressed the controversy in a detailed blog post.

Additional Information

• Meaning of the Options:
• Addressed: Dealt with or discussed a subject or issue.
• Suppressed: Stopped or restrained something from being expressed or known.
• Diverted: Shifted attention or focus elsewhere.
• Evaded: Avoided or escaped from something, often dishonestly or cleverly.
• Usage Tips: Always consider the context of the sentence (e.g., tone, tense, and intent) to select the most suitable option.

The correct answer is '2' i.e. Inflated .

Key Points

• The word "Turgid" is used to describe something that is swollen, inflated, or pompous in style or language.
• Option 2, "Inflated," is the most appropriate synonym for the given word as it conveys the same meaning of being overly swollen or exaggerated.
• Options like Concise, Simple, and Plain are antonyms of the word "Turgid" and therefore do not match its meaning.

Correct Usage: The professor’s turgid lecture was difficult to follow because of its inflated language and excessive details.

Additional Information

• Synonyms for Turgid: Inflated, Overblown, Pompous.
• Antonyms for Turgid: Concise, Simple, Plain, Unadorned.
• Example Sentence: The river became turgid after the heavy rainfall, overflowing its banks.

The correct answer is '3' i.e. Layered .

Key Points

• The word "Palimpsestic" refers to something that has multiple layers or traces of earlier forms underneath. It is often used metaphorically to describe something that has been reused or altered but still retains traces of its earlier state.
• The most appropriate synonym for this word is "Layered", which captures the idea of having multiple layers or levels.
• Other options like "Simplistic," "Erased," and "Empty" do not align with the meaning of "Palimpsestic." Specifically:
• "Simplistic": Refers to oversimplified ideas, not layers.
• "Erased": Refers to something removed, whereas palimpsestic retains traces of the past.
• "Empty": Refers to something void or without content, which is the opposite of layered.

Correct sentence: The document had a palimpsestic quality, with its layered history visible beneath the new text.

Additional Information

• Use of the word "Palimpsest": Originally, it referred to a manuscript on which the original writing had been erased to make room for new text but still retained traces of the old text.
• In modern usage, it is often used metaphorically to describe anything that shows evidence of its history or layers.
• Example: The city’s architecture is palimpsestic, with modern buildings standing alongside ruins from ancient times.

The correct answer is '3' i.e. Insouciant .

Key Points

• The word Insouciant is correctly spelt and means showing a lack of concern or care; carefree or relaxed.
• It is derived from the French word "insouciant," which means "carefree" or "unconcerned."
• Each of the other options contains spelling errors and does not accurately represent the correct word:
• Option 1: "Innocient" – Incorrect spelling of "Innocent."
• Option 2: "Insocant" – Not a valid English word.
• Option 4: "linsociant" – Incorrect and not a valid English word.

Correct usage: The child’s insouciant attitude was evident as he played happily, unaware of the storm approaching.

Additional Information

• Synonyms: Nonchalant, carefree, indifferent.
• Antonyms: Anxious, concerned, worried.
• Example Sentence: Despite the chaos around her, she remained insouciant and calm.

The correct answer is '1' i.e. Every small corner or hidden part .

Correct usage: The detectives searched every nook and cranny of the house for evidence.

Additional Information

• "Leave no stone unturned": Similar to "Every nook and cranny," it means to try every possible way or investigate thoroughly.
• "Dig deep": To put in significant effort to find something, especially information or resources.
• Usage Tips:
• Use this idiom in contexts where thoroughness or meticulous searching is highlighted.
• It can be applied to both physical searches (e.g., a house) or abstract searches (e.g., data or clues).

The correct answer is '3' i.e. Offend or annoy someone .

Key Points

• The idiom "Tread on your toes" means to offend or annoy someone, especially by interfering in their responsibilities or personal matters.
• It is often used in a figurative sense to describe situations where someone oversteps their boundaries or causes discomfort to another individual.
• The correct interpretation of this idiom aligns with option 3: "Offend or annoy someone."

Correct usage: Be careful not to tread on your boss's toes by taking decisions without consulting them first.

Additional Information

• Examples of Usage:
• She doesn't want to tread on anyone's toes, so she avoids discussing sensitive topics.
• He accidentally tread on his colleague's toes by taking over her project without informing her.

The correct answer is 'Worry'.

Key Points

• The passage describes the man as sitting alone, dressed in "frayed clothes," and his face was "creased" with a particular emotion.
• The description "gazing at the ground as if trying to find answers" suggests a state of deep concern, anxiety, or preoccupation with life's difficulties.
• "Worry" (चिंता) is the most appropriate word to describe a face "creased" by the burdens of life, especially in a context involving "setbacks" and "grief."
• "Happiness" (Option 1) contradicts the description of frayed clothes and a weak smile.
• "Anger" (Option 2) typically involves different facial expressions (like a scowl) and wouldn't lead to someone being "lost in thought" in a quiet, reflective way.
• "Confusion" (Option 4) implies a lack of understanding, but the phrase "creased with" is most idiomatically paired with "worry" or "age" to show the physical toll of a hard life.

Therefore, the correct answer is 'Option 3'.

Complete Passage Segment: *I was strolling through the park one night when I saw a man sitting by himself on a bench. He was dressed in frayed clothes, and his face was creased with (1)*worry  He looked lost in thought, gazing at the ground as if trying to find answers. I paused for a moment before going over to talk to him. When I said hello, he looked up and smiled weakly. He began talking to me about his life, including his triumphs and setbacks, love and grief. His stories were so enlightening, and his perspective (2). He got to his feet as the sun began to set and thanked me for the chance to hear about his experiences. "Sometimes, all we need is someone to hear us," he stated. His words lingered in my mind, bringing to mind the (3) of human connection. That night, I left the park humbled and (4)____. Life is full of unexpected encounters, each one with the power to (5)_____ us in ways that we  never thought possible.

Additional Information

• Frayed (घिसा हुआ): (Of fabric) unraveled or worn at the edge. It suggests the man may be going through a difficult financial or personal period.
• Creased: In this context, it refers to lines or wrinkles on the face caused by habitual expressions or stress.
• Contextual Reading: When solving Cloze Tests, look for the "mood" of the character. The mention of "setbacks" and "grief" later in the text confirms a somber mood.

The correct answer is 'Enlightened'.

Key Points

• The sentence structure is a parallel construction: "His stories were so enlightening, and his perspective enlightened."
• "Enlightened" (प्रबुद्ध/ज्ञानोदय) as a verb in this context suggests that the man's viewpoint was filled with wisdom and understanding. It perfectly matches the previous adjective "enlightening" to emphasize the profound nature of the conversation.
• While "Deepened" (Option 1) is a common collocation for perspectives, in specific exam contexts where "Enlightened" is provided as the key, it is chosen to maintain thematic consistency with the stories being "enlightening."
• "Shifted" (Option 2) suggests a change in direction, which isn't necessarily implied by the wisdom of the stories.
• "Worsened" (Option 4) is a negative term that contradicts the "humbled" and positive feeling the narrator describes at the end.

Therefore, the correct answer is 'Option 3'.

Complete Passage Segment: I was strolling through the park one night when I saw a man sitting by himself on a bench. He was dressed in frayed clothes, and his face was creased with (1)worry  He looked lost in thought, gazing at the ground as if trying to find answers. I paused for a moment before going over to talk to him. When I said hello, he looked up and smiled weakly. He began talking to me about his life, including his triumphs and setbacks, love and grief.

That night, I left the park humbled and (4)____. Life is full of unexpected encounters, each one with the power to (5)_____ us in ways that we  never thought possible.

Additional Information

• Enlightening (शिक्षाप्रद): Providing spiritual or intellectual insight.
• Parallelism in Cloze Tests: Examiners often use the same root word (enlighten/enlightening) or words with very similar meanings in the same sentence to reinforce a specific theme.
• Perspective (परिप्रेक्ष्य): A particular attitude toward or way of regarding something; a point of view.

The correct answer is 'Power'.

Key Points

• The man tells the narrator, "Sometimes, all we need is someone to hear us." This simple act has a profound effect on the narrator, who leaves the park "humbled."
• The final sentence of the passage reinforces this by mentioning the "power to (5)_________ us." This thematic link indicates that the narrator is reflecting on the strength or impact of that interaction.
• "Power" (शक्ति/सामर्थ्य) accurately describes the capacity of human connection to influence someone's mind and heart so deeply.
• "Importance" (Option 1) is a weaker synonym; while human connection is important, the passage emphasizes the transformative effect it has, which is better characterized as "power."
• "Beauty" (Option 2) focuses on the aesthetic or emotional quality, but the passage is more about the significant internal shift (being "humbled") caused by the encounter.
• "Fragility" (Option 4) means the quality of being easily broken. Nothing in the passage suggests that the connection was weak or easily destroyed.

Therefore, the correct answer is 'Option 3'.

Complete Passage Segment: I was strolling through the park one night when I saw a man sitting by himself on a bench.

Additional Information

• Lingered (ठहर जाना): To stay in a place longer than necessary because of a reluctance to leave. Here, it refers to his words staying in the narrator's thoughts.
• Human Connection: The sense of closeness and belongingness a person can experience when having supportive and positive relationships with another.
• Vocabulary Tip: In exams, look for concluding sentences to find clues for earlier blanks. The use of "power" in the final sentence is a direct clue for blank 3.

The correct answer is 'Inspired'.

Key Points

• The narrator describes the experience as "enlightening" and mentions that the man's words "lingered" in their mind, reminding them of the power of human connection.
• "Inspired" (प्रेरित) means filled with the urge or ability to do or feel something, especially something creative or positive. This fits the context of someone leaving an encounter feeling "humbled" and moved by the wisdom they received.
• "Energized" (Option 2) suggests a physical or active boost of energy. While the encounter was positive, the tone is quiet, reflective, and emotional rather than high-energy.
• "Discouraged" (Option 3) and "Depleted" (Option 4) are negative terms. Since the narrator found the encounter "enlightening" and powerful, they would not feel saddened or drained of energy.

Therefore, the correct answer is 'Option 1'.

Complete Passage Segment: I was strolling through the park one night when I saw a man sitting by himself on a bench.

Additional Information

• Humbled (विनम्र): To cause someone to feel less important or proud. In this context, it means the narrator felt a sense of modesty after hearing about the man's profound life struggles.
• Unexpected Encounters: A theme often found in Reading Comprehension passages that highlights how small, unplanned events can change one's outlook on life.
• Collocations: "Humbled and inspired" is a very common pair in English literature used to describe a transformative emotional experience.

The correct answer is 'Inspire'.

Key Points

• The concluding sentence sums up the emotional impact of the story: "Life is full of unexpected encounters, each one with the power to (5)_________ us..."
• "Inspire" (प्रेरित करना) means to fill someone with the urge or ability to do or feel something, especially something creative or positive. This is the central theme of the passage—a chance meeting that leaves a lasting, positive impression.
• The narrator has already stated they left the park "inspired" in the previous sentence. Using the verb form "inspire" here reinforces the main takeaway of the narrative.
• "Teach" (Option 1) is a factual outcome, but the tone of the passage is more emotional and transformative than merely educational.
• "Challenge" (Option 2) means to test one's abilities or beliefs. While the narrator's perspective changed, the overall "vibe" of the encounter was one of encouragement and shared humanity.
• "Overwhelm" (Option 4) usually implies being defeated or crushed by a feeling, which is too intense and potentially negative for this uplifting conclusion.

Therefore, the correct answer is 'Option 3'.

Additional Information

• Thematic Consistency: In competitive English sections, the conclusion of a story usually mirrors the emotions established in the "climax" or "turning point." Since the conversation was "enlightening," the result is "inspiration."
• Human Connection: The passage highlights the psychological importance of being heard, a theme often found in ethics-based reading comprehension sets.
• Grammar Tip: When a word appears as an adjective in one sentence (inspired), it is very common for the corresponding verb (inspire) to appear in the summary or concluding statement of the same passage.

The correct answer is '1' i.e. We are told stories by my grandmother .

Key Points

• The given sentence is in the present simple tense, as indicated by the verb "tells".
• When transforming an active sentence in the present simple tense into the passive voice, the structure is:
• Passive Voice Structure: Object + is/are + past participle + by + subject.
• In the given sentence:
• Subject: My grandmother
• Verb: tells
• Object: us stories
• When converted into the passive voice:
• Object (us stories): becomes the subject of the passive sentence.
• Verb (tells): changes to "are told" (present simple passive form).
• The subject (my grandmother) is moved after the verb with the preposition "by."

Correct sentence: We are told stories by my grandmother.

Additional Information

• Passive Voice Rules:
• In the passive voice, the focus shifts from the subject performing the action to the object receiving the action.
• The tense of the verb remains the same as in the active voice, but the verb is changed to its passive form.
• Examples:
• Active: She writes a letter. → Passive: A letter is written by her.
• Active: They make cakes. → Passive: Cakes are made by them.

The correct answer is '2' i.e. A rare species of bird was claimed to have been seen by him during his expedition to the Amazon rainforest .

Key Points

• The given sentence requires transformation into the passive voice.
• When converting to the passive voice, the object of the active sentence becomes the subject of the passive sentence.
• In this case, "a rare species of bird" becomes the subject of the passive voice sentence.
• The verb "claimed" requires the passive structure "was claimed to have been seen," which indicates a past event described in the passive voice.

Correct sentence: A rare species of bird was claimed to have been seen by him during his expedition to the Amazon rainforest.

Additional Information

• Active voice structure: Subject + verb + object.
• Example: He claimed to have seen a rare species of bird.
• Passive voice structure: Object + was/were + past participle + (by subject).
• Example: A rare species of bird was claimed to have been seen by him.
• The inclusion of "to have been seen" highlights that the event occurred prior to the claim being made.

The correct answer is '2' i.e. "Have you been to the new cafe that opened last week, and do you think it is better than the one we have been going to for months?" she asked him.

Key Points

• The given sentence is an example of converting indirect speech into direct speech.
• In direct speech, the actual words of the speaker are quoted within quotation marks.
• The tense and pronouns must be adjusted appropriately when converting indirect speech to direct speech, keeping the original meaning intact.
• The sentence in indirect speech mentions "had been to the new cafe that had opened the previous week," which needs to be converted to the present perfect tense "Have you been to the new cafe that opened last week" in direct speech.
• The second part of the indirect speech, "whether he thought it was better than the one they had been going to for months," is transformed to "do you think it is better than the one we have been going to for months" in direct speech.

Correct sentence: "Have you been to the new cafe that opened last week, and do you think it is better than the one we have been going to for months?" she asked him.

Additional Information

• Rules for Direct Speech:
• Enclose the exact words spoken by the speaker in quotation marks.
• Adjust pronouns, tenses, and time expressions as per the context.
• Example: Indirect: She said that she was happy. → Direct: She said, "I am happy."
• Rules for Indirect Speech:
• Modify the sentence to reflect the past tense when reporting speech.
• Example: Direct: She said, "I am happy." → Indirect: She said that she was happy.

The correct answer is '1' i.e. "You must tell me everything you saw this morning, as it could be the key to solving the case that has been haunting the city for a long time," the detective said to the witnesses .

Key Points

• The question is about converting an indirect speech into direct speech.
• The sentence in indirect speech states that "The detective told the witnesses that they must tell him everything they had seen that morning, as it could be the key to solving the case." The verb "must" in direct speech remains "must" as it indicates obligation in the present tense.
• The pronouns and verbs must be adjusted to match direct speech:
• “they” becomes “you” since the detective is addressing the witnesses directly.
• “had seen” becomes “saw” because in direct speech, the past perfect tense is often converted into the simple past tense to reflect the immediacy of the conversation.
• Options 2, 3, and 4 fail to accurately reflect the correct structure and verb usage for direct speech:
• Option 2 incorrectly uses "had to tell," which changes the meaning.
• Option 3 uses “had seen that morning,” which is unnecessary for direct speech.
• Option 4 incorrectly uses "tell him," which is inconsistent with the direct address in direct speech.

Correct sentence: "You must tell me everything you saw this morning, as it could be the key to solving the case that has been haunting the city for a long time," the detective said to the witnesses.

Additional Information

• Direct and Indirect Speech Rules:
• In direct speech, the exact words of the speaker are quoted and enclosed in quotation marks.
• In indirect speech, the speaker's words are reported without quotation marks, and pronouns, tenses, and adverbs of time/place are adjusted accordingly.
• Examples:
• Direct: He said, "I am going to the market now."
• Indirect: He said that he was going to the market then.

The correct answer is '1' i.e. principle, principal .

Key Points

• The sentence requires two homonyms that are spelled differently but sound similar and have different meanings.
• The word "principle" refers to a fundamental truth or guiding belief, which fits the context of "the core principle of fairness."
• The word "principal" refers to someone in a position of authority or importance, which aligns with the context of "the principal disagreed with her approach."

Correct sentence: The teacher's decision was guided by the core principle of fairness, even though the principal disagreed with her approach.

Additional Information

• Homonyms:
• Homonyms are words that sound the same but have different meanings and, sometimes, different spellings.
• Example: "principle" (a rule or belief) and "principal" (a person in charge).
• Common Misunderstandings:
• These two words are often confused due to their similar pronunciation.
• Remember: "Principle" relates to a concept or belief, while "Principal" can refer to a person or something of primary importance.

The correct answer is '4' i.e. defuse, diffuse .

Key Points

• The sentence requires two homonyms, which are words that sound similar or the same but have different meanings.
• In the given sentence, the first blank refers to calming or neutralizing the tension in the room, which matches the meaning of "defuse".
• The second blank requires a word that fits the context of spreading into a larger conflict, which aligns with the meaning of "diffuse".
• Both words are correctly used in their respective contexts in the sentence.

Correct sentence: The negotiator managed to defuse the tension in the room before it could diffuse into a full-blown conflict.

Shortcut Trick

Assume P = 6 units.

Q = 2.5 × 6 = 15 units and S = 60% of 15 = 9 units.

Since R is the average of P, Q, R, S ⇒ 3R = P + Q + S = 6 + 15 + 9 = 30 units ⇒ R = 10 units.

Given P + R = 6 + 10 = 16 units = ₹4800 ⇒ 1 unit = ₹300.

Amount of R = 10 units × 300 = ₹3000.

∴ The correct answer is Rs. 3000.

Alternate Method

Given:

Q = 2.5P | S = Q − 40% of Q = 0.6Q | R = (P + Q + R + S) ÷ 4 | P + R = Rs. 4800

Calculations:

⇒ Q = 2.5P

⇒ S = 0.6 × 2.5P = 1.5P

⇒ R = (P + 2.5P + R + 1.5P) ÷ 4

⇒ 4R = 5P + R

⇒ 3R = 5P ⇒ P = (3 ÷ 5)R = 0.6R

⇒ Given P + R = 4800

⇒ 0.6R + R = 4800

⇒ 1.6R = 4800

⇒ R = 4800 ÷ 1.6 = 3000

∴ The correct answer is Rs. 3000.

⇒ Selling price of 1 kg sugar = 450 ÷ 15

⇒ Selling price of 1 kg sugar = 30

⇒ Profit = Selling price of 3 kg sugar = 3 × 30

⇒ Profit = 90

⇒ Cost price = Selling price - Profit

⇒ Cost price = 450 - 90

⇒ Cost price = 360

⇒ Profit percentage = (Profit ÷ Cost price) × 100

⇒ Profit percentage = (90 ÷ 360) × 100

⇒ Profit percentage = 25%

∴ The correct answer is option 2.

Given:

Gain = 25%

⇒ 3 × 100 = 300

⇒ 4 × 100 = 400

⇒ 200 × 150 ÷ 100 = 300

⇒ 300 × 140 ÷ 100 = 420

⇒ 400 × 130 ÷ 100 = 520

⇒ Ratio = 300 : 420 : 520

⇒ Divide by 20

⇒ Ratio = 15 : 21 : 26

∴ The correct answer is 15 : 21 : 26.

Given:

Number of students = 24

Calculation:

⇒ Initial sum = 24 × 15 = 360

⇒ New sum (with 1 teacher) = 25 × 16 = 400

⇒ First teacher age = 400 - 360 = 40

⇒ New sum (with 2 teachers) = 26 × 17 = 442

⇒ Second teacher age = 442 - 400 = 42

∴ The correct answer is 42.

Shortcut Trick

The Speed Ratio is 80 : 60 = 4 : 3.

Since distance is constant, the Time Ratio is the inverse = 3 : 4.

The difference in time units is 4 − 3 = 1 unit, which corresponds to 2 hours (1 hr early to 1 hr late).

Actual time taken at 80 km/h = 3 units × 2 = 6 hours.

Distance = Speed × Time = 80 km/h × 6 hours = 480 km.

∴ The correct answer is 480 km.

Alternate Method

Given:

Speed 1 (S₁) = 80 km/h (reaches 1 hr early)

Speed 2 (S₂) = 60 km/h (reaches 1 hr late)

Total time difference (ΔT) = 1 − (−1) = 2 hours

Formula Used:

Distance = [(S₁ × S₂) / (S₁ − S₂)] × ΔT

Calculations:

⇒ Distance = (80 × 60) / (80 − 60) × 2

⇒ Distance = (4800 / 20) × 2

⇒ Distance = 240 × 2

⇒ Distance = 480 km

⇒ Therefore, the correct option is (3).

∴ The correct answer is 480 km.

Additional Information

Relationship between Speed and Time

When distance is constant, speed is inversely proportional to time (Speed ∝ 1/Time). If speed increases by a factor of x/y, time decreases by the reciprocal factor.

Average Speed Formula

For a round trip or two equal distances with speeds x and y, the average speed is given by (2 × x × y) / (x + y).

Time Difference Calculation

When comparing 'early' and 'late' timings, the total time difference is the sum of the early and late durations (Early + Late).

Shortcut Trick

Ratio of Final Salary to Original Salary = 156.25 : 100 = 1.5625.

For two equal successive increments, the Multiplying Factor for each step is √(Total Change Factor).

Step Factor = √1.5625 = 1.25.

Percentage increase = (1.25 − 1) × 100 = 25%.

∴ The correct answer is 25%.

Alternate Method

Given: Final salary = 156.25% of original salary. Number of increments = 2. Both increments are equal.

Formula Used: Final Value = Initial Value × (1 + r/100)ⁿ

Let the Original Salary be 100 and Increment be x%.

⇒ Final Salary = 100 × (1 + x/100) × (1 + x/100)

⇒ 156.25 = 100 × (1 + x/100)²

⇒ 156.25 / 100 = (1 + x/100)²

⇒ 1.5625 = (1 + x/100)²

⇒ √1.5625 = 1 + x/100

⇒ 1.25 = 1 + x/100

⇒ x/100 = 1.25 − 1 = 0.25

⇒ x = 25%

∴ The correct answer is 25%.

Additional Information

Successive Percentage Formula

For two successive changes of a% and b%, the net percentage change is given by the formula [a + b + (ab/100)]%.

Reverse Square Root Method

When n equal successive changes result in a total factor F, each single change factor is found by taking the n^th root of F (i.e., F^1/n).

Compounding Relationship

Successive increments follow the same logic as Compound Interest, where the principal increases by a fixed rate over multiple periods.

Given:

Initial population = 240000

Birth rate = 12%

Death rate = 7%

Time = 3 years

Formula Used:

Net increase = (1 + increase/100) × (1 - decrease/100)

Population after t years = P × (net factor)^t

Calculation:

⇒ Net factor = 1.12 × 0.93

⇒ Net factor = 1.0416

⇒ Population after 3 years = 240000 × (1.0416)³

⇒ (1.0416)² = 1.085

⇒ (1.0416)³ = 1.130

⇒ Population = 240000 × 1.130

⇒ Population = 271200

∴ The correct answer is 271200.

Given:

A = 8 days

B = 16 days

Formula Used:

Work = LCM of times

Efficiency = Work ÷ Time

Total time = Total work ÷ Total efficiency

Calculation:

⇒ LCM of 8 and 16 = 16

⇒ Efficiency of A = 16 ÷ 8 = 2

⇒ Efficiency of B = 16 ÷ 16 = 1

⇒ Total efficiency = 2 + 1 = 3

⇒ Time = 16 ÷ 3

⇒ Time = $5\frac{1}{3}$

∴ The correct answer is $5\frac{1}{3}$.

Given:

Marked price = 1200

First discount = 20%

Second discount = 10%

Calculation:

⇒ Selling price = 1200 × (1 - 20/100) × (1 - 10/100)

⇒ Selling price = 1200 × 0.8 × 0.9

⇒ Selling price = 1200 × 0.72

⇒ Selling price = 864
