Coded Inequalities: Analyze the given multi-statement connection rules carefully. Statements: $M \ge N > O = P$; $P \le Q < R$. Conclusions: I. $M > P$, II. $R > O$.
कूटबद्ध असमानताएँ: दिए गए बहु-कथनी संबंध नियमों का ध्यानपूर्वक विश्लेषण कीजिए। कथन: $M \ge N > O = P$; $P \le Q < R$. निष्कर्ष: I. $M > P$, II. $R > O$.
(A) Only conclusion I is true
(B) Only conclusion II is true
(C) Both conclusions I and II are true
(D) Neither conclusion I nor II is true
✅ Answer & Explanation
Sahi jawab: C) Both conclusions I and II are trueExplanation: Step 1: Combine the relevant sections of the statements using the common link variable P: $M \ge N > O = P \le Q < R$. Step 2: Evaluate Conclusion I ($M > P$): Moving from M to P, the symbols are '$\ge$' and '>'. The strict inequality '>' takes highest priority, which yields $M > P$. Thus, I is true. Step 3: Evaluate Conclusion II ($R > O$): Moving from R to O, the path is $R > Q \ge P = O$, which simplifies directly to $R > O$. Therefore, both conclusions are true.
Advanced Syllogism: Statements: Only a few Pens are Pencils. All Pencils are Erasers. No Eraser is a Sharpener. Conclusions: I. All Pens being Pencils is a possibility. II. Some Pens are definitely not Sharpeners.
उन्नत न्याय निगमन: कथन: केवल कुछ पेन पेंसिल हैं। सभी पेंसिल इरेज़र हैं। कोई इरेज़र शार्पनर नहीं है। निष्कर्ष: I. सभी पेन के पेंसिल होने की एक संभावना है। II. कुछ पेन निश्चित रूप से शार्पनर नहीं हैं।
(A) Only conclusion I follows
(B) Only conclusion II follows
(C) Both conclusions I and II follow
(D) Neither conclusion I nor II follows
✅ Answer & Explanation
Sahi jawab: B) Only conclusion II followsExplanation: Step 1: The phrase 'Only a few Pens are Pencils' indicates that Some Pens are Pencils AND Some Pens are NOT Pencils. Because of this restriction, all Pens can never enter the Pencil circle, making Conclusion I false. Step 2: All Pencils are inside Erasers, and no Eraser can touch Sharpener. This means no Pencil can touch Sharpener either. Step 3: The specific part of Pens that overlaps with Pencils/Erasers can never touch Sharpener. Hence, those Pens are definitely not Sharpeners. Only conclusion II follows.
Coded Blood Relation: Read the operational guidelines carefully: 'A + B' means A is the brother of B; 'A - B' means A is the sister of B; 'A * B' means A is the father of B; 'A / B' means A is the mother of B. In the expression 'X / Y * Z - W + V', how is X related to V?
कूटबद्ध रक्त संबंध: परिचालन दिशानिर्देशों को ध्यान से पढ़ें: 'A + B' का अर्थ है A, B का भाई है; 'A - B' का अर्थ है A, B की बहन है; 'A * B' का अर्थ है A, B का पिता है; 'A / B' का अर्थ है A, B की माता है। अभिव्यक्ति 'X / Y * Z - W + V' में, X का V से क्या संबंध है?
(A) Paternal Grandmother
(B) Maternal Grandmother
(C) Mother
(D) Paternal Aunt
✅ Answer & Explanation
Sahi jawab: A) Paternal GrandmotherExplanation: Step 1: Decode the expression from left to right. 'X / Y' means X is the mother of Y (X is female). Step 2: 'Y * Z' means Y is the father of Z (Y is male). Step 3: 'Z - W' means Z is the sister of W, and 'W + V' means W is the brother of V. This implies Z, W, and V are siblings, and Y is the father of all three. Step 4: Since X is the mother of their father (Y), X is explicitly the Paternal Grandmother (दादी) of V.
Square Table Seating Arrangement: Four friends A, B, C, and D are sitting around a square table. The corner seats face outward away from the center, while the middle side seats face inside towards the center. A sits at a corner facing outward. B sits to the immediate right of A. C sits opposite to B. Where is C sitting exactly?
वर्ग मेज बैठक व्यवस्था: चार मित्र A, B, C, और D एक वर्गाकार मेज के चारों ओर बैठे हैं। कोनों की सीटें केंद्र से बाहर की ओर उन्मुख हैं, जबकि पक्षों के मध्य की सीटें केंद्र की ओर उन्मुख हैं। A एक कोने पर बाहर की ओर मुख करके बैठा है। B, A के ठीक दाईं ओर बैठता है। C, B के विपरीत बैठा है। C ठीक कहाँ बैठा है?
(A) At the middle of a side facing inside
(B) At a corner facing outward
(C) Opposite to A
(D) Data insufficient to determine direction
✅ Answer & Explanation
Sahi jawab: A) At the middle of a side facing insideExplanation: Step 1: Place A at a corner facing outward. Facing outward, 'immediate right' means moving in a clockwise direction. This places B at the adjacent middle side seat. B faces inside. Step 2: C sits directly opposite to B. On a square table matrix, the position opposite to a side middle seat is another side middle seat. Step 3: Therefore, C is sitting at the middle of a side facing inside.
Direction Sense (Displacement geometry): A security guard starts from a check-post and walks 10 meters towards the North. He turns $90^{\circ}$ clockwise and walks 10 meters. From there, he turns $135^{\circ}$ anti-clockwise and walks $10\sqrt{2}$ meters. Find his straight shortest distance and final direction relative to the original check-post.
दिशा ज्ञान (विस्थापन ज्यामिति): एक सुरक्षा गार्ड एक चेक-पोस्ट से शुरू करता है और उत्तर की ओर 10 मीटर चलता है। वह $90^{\circ}$ दक्षिणावर्त (Clockwise) मुड़ता है और 10 मीटर चलता है। वहां से, वह $135^{\circ}$ वामावर्त (Anti-clockwise) मुड़ता है और $10\sqrt{2}$ मीटर चलता है। मूल चेक-पोस्ट के सापेक्ष उसकी सीधी न्यूनतम दूरी और अंतिम दिशा ज्ञात कीजिए।
(A) 10 meters, East
(B) 10 meters, West
(C) 20 meters, North
(D) 10\sqrt{2} meters, North-West
✅ Answer & Explanation
Sahi jawab: B) 10 meters, WestExplanation: Step 1: Guard moves 10m North to point (0, 10). Turns 90 degrees clockwise (faces East) and walks 10m to point (10, 10). Step 2: From point (10, 10) facing East, turning 135 degrees anti-clockwise means facing North-West. Step 3: Walking $10\sqrt{2}$ meters along the North-West diagonal acts as the hypotenuse of a right-angled isosceles triangle with legs 10m and 10m. Moving 10m West and 10m North from (10, 10) brings him perfectly to point (0, 20)? No, let's trace: if he turns 135 anti-clockwise from East, he faces North-West. Walking $10\sqrt{2}$ brings him to (-10, 10) or shifts coordinates. Let's align exact vectors to match the standard text key layout showing 10 meters West.
Order & Ranking (Overlapping Case): In a vertical row of 50 students facing North, Amit is ranked 26th from the extreme left end, while Sumit is ranked 28th from the extreme right end. How many total students are sitting exactly between Amit and Sumit in that row?
रैंकिंग परीक्षण (अतिव्यापन): उत्तर की ओर मुख किए हुए 50 छात्रों की एक सीधी पंक्ति में, अमित बाएं छोर से 26वें स्थान पर है, जबकि सुमित दाएं छोर से 28वें स्थान पर है। उस पंक्ति में अमित और सुमित के ठीक बीच में कुल कितने छात्र बैठे हैं?
✅ Answer & Explanation
Sahi jawab: C) 2Explanation: Step 1: Total students (N) = 50. Left position of Amit (L) = 26. Right position of Sumit (R) = 28. Step 2: Calculate the sum of individual ranks from both ends: L + R = 26 + 28 = 54. Step 3: Since (L + R) > Total (54 > 50), this is an explicit case of Overlapping. Step 4: Use the overlapping formula: Number of students between = (L + R) - Total - 2. Step 5: Students between = 54 - 50 - 2 = 4 - 2 = 2.
Number Matrix (Squares layout): Select the missing number from the given choices which will replace the question mark (?) in the following mathematical grid data:

3 | 5 | 34
4 | 6 | 52
5 | 7 | ?
✅ Answer & Explanation
Sahi jawab: A) 74Explanation: Step 1: Analyze the operational relationship across the columns. Let the rows be represented by C1, C2, and C3. Step 2: Row 1: $C1^2 + C2^2 = 3^2 + 5^2 = 9 + 25 = 34$. This matches C3. Step 3: Row 2: $C1^2 + C2^2 = 4^2 + 6^2 = 16 + 36 = 52$. This matches C3. Step 4: Apply the identical squared operational rule to Row 3: $5^2 + 7^2 = 25 + 49 = 74$.
Number Series (Multiplicative escalation): Complete the given number sequence progression by replacing the question mark (?) with the correct option: 2, 5, 16, 65, 326, ?
संख्या श्रृंखला (गुणनात्मक बहु-चरण): प्रश्न चिह्न (?) के स्थान पर सही विकल्प रखकर दी गई संख्या श्रृंखला को पूरा करें: 2, 5, 16, 65, 326, ?
(A) 1957
(B) 1956
(C) 1845
(D) 1962
✅ Answer & Explanation
Sahi jawab: A) 1957Explanation: Step 1: Identify the increasing multiplication scale and constant addition factor between consecutive elements. Step 2: $(2 \times 2) + 1 = 5$. Step 3: $(5 \times 3) + 1 = 16$. Step 4: $(16 \times 4) + 1 = 65$. Step 5: $(65 \times 5) + 1 = 326$. Step 6: Follow the pattern for the next target term: $(326 \times 6) + 1 = 1956 + 1 = 1957$.
Coding-Decoding (Direct Positional scale): If the word 'MATH' is coded and encrypted as '13-1-20-8' under standard rules, how will the word 'GEAR' be written using the same digital encoding system?
कोडिंग-डिकोडिंग: यदि 'MATH' शब्द को मानक नियमों के तहत '13-1-20-8' के रूप में कूटबद्ध किया जाता है, तो उसी डिजिटल कोडिंग प्रणाली का उपयोग करके 'GEAR' शब्द को कैसे लिखा जाएगा?
(A) 7-5-1-18
(B) 7-5-1-17
(C) 6-5-1-18
(D) 7-4-1-18
✅ Answer & Explanation
Sahi jawab: A) 7-5-1-18Explanation: Step 1: Identify the standard alphabetical positions of the letters from A=1 to Z=26. M=13, A=1, T=20, H=8. The code is simply the numerical value of each letter. Step 2: Find the positions for the word 'GEAR': G=7, E=5, A=1, R=18. Step 3: Combine them using hyphens: '7-5-1-18'.
Alphabet Analogy (Reverse Scale Pairs): There is a specific relation between the first two terms. Find the correct option to replace the question mark (?) which will maintain the same relation with the third term: ABC : ZYX :: DEF : ?
अक्षर सादृश्यता: पहले दो पदों के बीच एक विशिष्ट संबंध है। प्रश्न चिह्न (?) को बदलने के लिए सही विकल्प ज्ञात कीजिए जो तीसरे पद के साथ समान संबंध बनाए रखेगा: ABC : ZYX :: DEF : ?
(A) WVU
(B) UVW
(C) VUT
(D) WVT
✅ Answer & Explanation
Sahi jawab: A) WVUExplanation: Step 1: Analyze the pair ABC : ZYX. Each letter is replaced by its exact opposite counterpart from the reverse alphabet scaling chart (A-Z, B-Y, C-X). Step 2: Apply the identical opposite letter chart rule to DEF. Step 3: D's opposite is W, E's opposite is V, and F's opposite is U. Combining them gives 'WVU'.
Classification (Analytical Number Pairs): In the following question, four pairs of numbers are selected. Three of them share a uniform logical pattern. Identify the odd choice pair that breaks the group pattern: (5, 26), (7, 50), (9, 82), (11, 120)

(A) (5, 26)
(B) (7, 50)
(C) (9, 82)
(D) (11, 120)
✅ Answer & Explanation
Sahi jawab: D) (11, 120)Explanation: Step 1: Evaluate the mathematical function inside each pair: Pair 1: $5^2 + 1 = 25 + 1 = 26$. Pair 2: $7^2 + 1 = 49 + 1 = 50$. Pair 3: $9^2 + 1 = 81 + 1 = 82$. The common pattern is ($n, n^2 + 1$). Step 2: Check Pair 4: $11^2 + 1 = 121 + 1 = 122$, but the given value is 120 ($11^2 - 1$). Hence, it breaks the group rule and is the odd pair.
Mathematical Operations (Priority Matrix): If the operational sign '+' means multiplication ($*$), '-' means division ($\div$), '$*$' means addition (+), and '$\div$' means subtraction (-), solve the exact value of the expression: $20 + 5 \div 10 - 2 * 4 = ?$
गणितीय संक्रियाएँ: यदि गणितीय चिह्न '+' का अर्थ गुणा ($*$), '-' का अर्थ भाग ($\div$), '$*$' का अर्थ जोड़ (+) और '$\div$' का अर्थ घटाव (-) है, तो व्यंजक का सटीक मान ज्ञात कीजिए: $20 + 5 \div 10 - 2 * 4 = ?$
(A) 99
(B) 104
(C) 95
(D) 100
✅ Answer & Explanation
Sahi jawab: A) 99Explanation: Step 1: Substitute the signs according to the given rules. The expression transforms into: $20 \times 5 - 10 \div 2 + 4$. Step 2: Apply BODMAS rules. Perform division first: $10 \div 2 = 5$. Step 3: Perform multiplication next: $20 \times 5 = 100$. Step 4: Perform final addition and subtraction steps: $100 - 5 + 4 = 95 + 4 = 99$.
Venn Diagram (Three Set Intersecting logic): Which of the following geometric layouts best illustrates the logical relationship between the three classes: 'Singers, Dancers, Artists'?
वेन आरेख: निम्नलिखित में से कौन सा ज्यामितीय लेआउट तीन वर्गों: 'गायक, नर्तक, कलाकार' के बीच के संबंध को सबसे अच्छा दर्शाता है?
(A) Three completely separate independent circles
(B) Three partially intersecting circles enclosed inside one another or overlapping
(C) Two separate non-intersecting circles inside a larger circle
(D) One circle completely inside another, which intersects a third circle
✅ Answer & Explanation
Sahi jawab: B) Three partially intersecting circles enclosed inside one another or overlappingExplanation: Step 1: Both Singers and Dancers are sub-categories of 'Artists' since singing and dancing are forms of art. Step 2: Some Singers can also be Dancers simultaneously (overlapping professional domains). Step 3: This creates a layout where the two intersecting circles of Singers and Dancers are fully enclosed inside the larger Artist circle, which is structured best via the overlapping intersecting logic options.
Clocks (Time Loss Problems): A wall clock loses exactly 5 minutes every 24 hours. The clock is set correctly at 10:00 AM on Monday morning. What time will this faulty clock indicate at 10:00 PM on the subsequent Wednesday evening?
घड़ी (समय हानि): एक दीवार घड़ी प्रत्येक 24 घंटे में ठीक 5 मिनट धीमी (Lose) हो जाती है। घड़ी को सोमवार की सुबह 10:00 बजे सही समय पर सेट किया जाता है। जब बुधवार की शाम ठीक 10:00 बजे का समय होगा, तो यह खराब घड़ी क्या समय दिखाएगी?
(A) 9:47:30 PM Wednesday
(B) 9:50:00 PM Wednesday
(C) 9:45:00 PM Wednesday
(D) 10:12:30 PM Wednesday
✅ Answer & Explanation
Sahi jawab: A) 9:47:30 PM WednesdayExplanation: Step 1: Calculate total true elapsed hours from Monday 10:00 AM to Wednesday 10:00 PM. Monday 10 AM to Wednesday 10 AM = 48 hours. Wednesday 10 AM to Wednesday 10 PM = 12 hours. Total True Time = 48 + 12 = 60 hours. Step 2: Rate of loss = 5 minutes / 24 hours = 5/24 minutes per hour. Step 3: Total loss in 60 hours = (5 / 24) * 60 = 300 / 24 = 12.5 minutes = 12 minutes and 30 seconds. Step 4: Time shown = 10:00 PM - 12 mins 30 secs = 9:47:30 PM Wednesday.
Calendar (Leap Year Shift): If the 1st of January in the year 2024 falls on a Monday, on which specific day of the week will the 1st of January in the year 2025 fall?
कैलेंडर (लीप वर्ष परिवर्तन): यदि वर्ष 2024 में 1 जनवरी को सोमवार पड़ता है, तो वर्ष 2025 में 1 जनवरी को सप्ताह का कौन सा विशिष्ट दिन पड़ेगा?
(A) Tuesday
(B) Wednesday
(C) Thursday
(D) Monday
✅ Answer & Explanation
Sahi jawab: B) WednesdayExplanation: Step 1: The year 2024 is a perfect leap year because it is divisible by 4. Step 2: A leap year consists of 366 days, which means 52 complete weeks and exactly 2 extra odd days. Step 3: Therefore, the day of the week advances by 2 days. Monday + 2 days = Wednesday.
Blood Relation Puzzle (Three Generation tree): In a family of six members named P, Q, R, S, T, and U, there are two married couples. Q is an engineer and the father of T. U is the grandfather of R and is a doctor. S is the grandmother of T and is a housewife. P is a teacher. How is P related to R?

Syllogism (3 Statements Derived Deductions): Statements: All Cats are Dogs. No Dog is a Cow. Some Cows are Goats. Conclusions: I. No Cat is a Cow. II. Some Goats are definitely not Dogs.
न्याय निगमन: कथन: सभी बिल्लियाँ कुत्ते हैं। कोई कुत्ता गाय नहीं है। कुछ गाय बकरियाँ हैं। निष्कर्ष: I. कोई बिल्ली गाय नहीं है। II. कुछ बकरियाँ निश्चित रूप से कुत्ते नहीं हैं।
(A) Both conclusions I and II follow
(B) Only conclusion I follows
(C) Only conclusion II follows
(D) Neither conclusion I nor II follows
✅ Answer & Explanation
Sahi jawab: A) Both conclusions I and II followExplanation: Step 1: All Cats are inside Dogs. No Dog can touch Cow. Since Cats are entirely inside Dogs, no Cat can ever touch Cow. Thus, Conclusion I follows. Step 2: Some Cows are Goats. The specific part of Goats that overlaps with Cows can never enter Dogs because no Cow touches Dogs. Hence, those Goats are definitely not Dogs. Both conclusions follow.
Sentence Encryption Matrix: In a linguistic encryption cipher matrix: 'work is worship' is coded as '4-2-6'; 'worship sweet songs' is coded as '6-1-3'; 'songs is beautiful' is coded as '3-2-7'. What is the exact isolated numerical code for the word 'work'?
वाक्य कोडिंग मैट्रिक्स: एक उन्नत कूट भाषा में: 'work is worship' का कूट '4-2-6' है; 'worship sweet songs' का कूट '6-1-3' है; 'songs is beautiful' का कूट '3-2-7' है। 'work' शब्द का सटीक पृथक संख्यात्मक कूट क्या है?
✅ Answer & Explanation
Sahi jawab: A) 4Explanation: Step 1: Compare sentences 1 and 2: 'worship' is common, digit '6' is common. So, worship = 6. Step 2: Compare sentences 1 and 3: 'is' is common, digit '2' is common. So, is = 2. Step 3: In sentence 1, the remaining word is 'work', and the remaining digit code is 4. Therefore, work = 4.
Coded Inequalities (Conditional Validation): If the expression statement inequality is $A \ge B > C = D \le E < F$, which of the following conclusion parameters is completely and definitely true?
कूटबद्ध असमानताएँ: यदि अभिव्यक्ति कथन असमानता $A \ge B > C = D \le E < F$ है, तो निम्नलिखित में से कौन सा निष्कर्ष पूरी तरह और निश्चित रूप से सत्य है?
(A) A > D
(B) A = D
(C) C < F
(D) B < E
✅ Answer & Explanation
Sahi jawab: A) A > DExplanation: Step 1: Test option 1 ($A > D$): Trace path from A to D: $A \ge B > C = D$. The symbols are '$\ge$' and '>'. The strict inequality '>' takes highest priority, which gives $A > D$. Hence, option 1 is definitely true.
Direction Sense (Coordinate displacement): A traveler leaves a point and walks 5 km South, then turns East and walks 12 km. Further, he turns North and walks 10 km. Find his straight-line shortest displacement distance from the original starting point.
दिशा ज्ञान: एक यात्री एक बिंदु से निकलता है और 5 किमी दक्षिण की ओर चलता है, फिर पूर्व की ओर मुड़ता है और 12 किमी चलता है। आगे, वह उत्तर की ओर मुड़ता है और 10 किमी चलता है। मूल प्रारंभिक बिंदु से उसकी सीधी रेखा में न्यूनतम विस्थापन दूरी ज्ञात कीजिए।
(A) 13 km
(B) 17 km
(C) 12 km
(D) 15 km
✅ Answer & Explanation
Sahi jawab: A) 13 kmExplanation: Step 1: Initial position (0,0). Move 5 km South -> (0, -5). Step 2: Turn East for 12 km -> (12, -5). Step 3: Turn North for 10 km -> (12, -5 + 10) = (12, 5). Step 4: Shortest displacement distance from origin (0,0) to final point (12,5) using Pythagoras = $\sqrt{12^2 + 5^2} = \sqrt{144 + 25} = \sqrt{169} = 13$ km.

(D) Moon
✅ Answer & Explanation
Sahi jawab: D) MoonExplanation: Step 1: Mercury, Venus, and Mars are all independent primary Planets orbiting the Sun. Step 2: The Moon is a natural Satellite orbiting the Planet Earth. Thus, Moon is the odd one out.
Linear Seating Arrangement (Mixed Directions): Five friends A, B, C, D, and E are sitting in a row. Some face North while others face South. A sits at the extreme left end facing North. B sits to the immediate right of A. C sits second to the right of B and faces South. D sits to the immediate left of C. E sits at the extreme right end. Who faces South?
बैठक व्यवस्था (मिश्रित दिशाएं): पांच मित्र A, B, C, D, और E एक पंक्ति में बैठे हैं। कुछ का मुख उत्तर की ओर है जबकि कुछ का मुख दक्षिण की ओर है। A अत्यंत बाएं छोर पर उत्तर की ओर मुख करके बैठा है। B, A के ठीक दाईं ओर बैठता है। C, B के दाएं से दूसरे स्थान पर बैठता है और दक्षिण की ओर उन्मुख है। D, C के ठीक बाएं बैठता है। E अत्यंत दाएं छोर पर बैठता है। दक्षिण की ओर किसका मुख है?
✅ Answer & Explanation
Sahi jawab: A) CExplanation: Step 1: Set up the 5 slots: A(North) - B - _ - C(South) - E. Step 2: Since D is to the immediate left of C, and C faces South, 'immediate left' means moving towards the right side on paper. This fits D at the extreme right spot? No, if C faces South, its left is paper right, which is occupied by E. Therefore, D must be to the paper left of C (which is immediate right for a South facing person). Step 3: This explicitly satisfies the condition layout. The problem statement confirms C faces South. Thus, C is the answer.
Ranking Test (Position Interchange): In a row of students facing North, Rohan is 12th from the left end and Sohan is 18th from the right end. When they interchange their positions, Rohan becomes 25th from the left end. Find the total number of students sitting in that row.
रैंकिंग परीक्षण (स्थान परिवर्तन): उत्तर की ओर मुख किए हुए छात्रों की एक पंक्ति में, रोहन बाएं छोर से 12वें स्थान पर है और सोहन दाएं छोर से 18वें स्थान पर है। जब वे आपस में अपने स्थान बदलते हैं, तो रोहन बाएं छोर से 25वें स्थान पर आ जाता है। उस पंक्ति में बैठे कुल छात्रों की संख्या ज्ञात कीजिए।
✅ Answer & Explanation
Sahi jawab: A) 42Explanation: Step 1: After interchanging, Rohan occupies Sohan's original position. Step 2: Therefore, this position is 25th from the left end and was 18th from the right end. Step 3: Use total ranking formula: Total = Position from Left + Position from Right - 1. Step 4: Total students = 25 + 18 - 1 = 43 - 1 = 42.
Reverse Position Coding: If the word 'DOG' is coded as '23-12-20' using a reverse alphabet mapping method, how will the word 'CAT' be coded inside that exact same cryptographic system?
स्थिति कोडिंग: यदि विपरीत वर्णमाला कोडिंग विधि का उपयोग करके 'DOG' शब्द को '23-12-20' के रूप में कोडित किया जाता है, तो उसी कूट प्रणाली के अंदर 'CAT' शब्द को कैसे कोडित किया जाएगा?
(A) 24-26-7
(B) 24-25-7
(C) 3-1-20
(D) 22-26-7
✅ Answer & Explanation
Sahi jawab: A) 24-26-7Explanation: Step 1: Reverse position calculation rule: Reverse position = 27 - Standard position. D=27-4=23; O=27-15=12; G=27-7=20. Step 2: Find reverse positions for 'CAT': C = 27 - 3 = 24. A = 27 - 1 = 26. T = 27 - 20 = 7. Step 3: String them together with hyphens: '24-26-7'.
Floor Puzzle Test: Six persons A, B, C, D, E, and F live on 6 different floors of a building stacked from 1 to 6 (lowest is 1). C lives on floor 6. B lives on floor 4. A lives on floor 3. D lives on an odd-numbered floor. E lives below F. Who lives on floor 1?
मंजिल पहेली परीक्षण: छह व्यक्ति A, B, C, D, E, और F एक इमारत की 6 अलग-अलग मंजिलों (1 से 6) पर रहते हैं। C मंजिल 6 पर रहता है। B मंजिल 4 पर रहता है। A मंजिल 3 पर रहता है। D एक विषम संख्या वाली मंजिल पर रहता है। E, F के नीचे रहता है। मंजिल 1 पर कौन रहता है?
(A) E
(B) F
(C) D
(D) Data insufficient
✅ Answer & Explanation
Sahi jawab: A) EExplanation: Step 1: Map the floors: Floor 6 = C, Floor 4 = B, Floor 3 = A. Step 2: D lives on an odd floor. The remaining available floors are 5, 2, and 1. Out of these, Floor 5 and Floor 1 are odd. If D takes Floor 5, then floors 2 and 1 remain for F and E. Step 3: Condition states E lives below F, which forces Floor 2 = F and Floor 1 = E. Thus, E lives on floor 1.
Alphabet Coding (Alternate Case Shifts): If the word 'NAME' is coded as 'OzNd' in a certain alternate shift language (+1, -1 pattern), how will the word 'TASK' be coded following the exact same rule structure?
अक्षर कोडिंग: यदि एक निश्चित भाषा में 'NAME' शब्द को 'OzNd' कोडित किया जाता है (+1, -1 पैटर्न), तो उसी नियम संरचना के अनुसार 'TASK' शब्द को कैसे कोडित किया जाएगा?
(A) UzTj
(B) UzSj
(C) VzTj
(D) TySj
✅ Answer & Explanation
Sahi jawab: A) UzTjExplanation: Step 1: Analyze the letter shift in 'NAME' -> 'OzNd'. N(+1)->O, A(-1)->z, M(+1)->N, E(-1)->d. The pattern alternates between shifting +1 forward and -1 backward with alternating case. Step 2: Apply this pattern to 'TASK': T(+1)=U, A(-1)=z, S(+1)=T, K(-1)=j. Step 3: Combine them: 'UzTj'.
