Analogy: Select the option that shares the exact same logical relationship as shown: $8 : 81 :: 64 : ?$.
सादृश्यता: उस विकल्प का चयन कीजिए जो दिखाए गए समान तार्किक संबंध को साझा करता है: $8 : 81 :: 64 : ?$.
(A) 625
(B) 512
(C) 125
(D) 729
✅ Answer & Explanation
Sahi jawab: A) 625Explanation: Step 1: Analyze the first pair: $8 = 2^3$ and $81 = 3^4$. The logic is $n^3 : (n+1)^4$. Step 2: Apply the same logic to the second pair: $64 = 4^3$. The next term must be $(4+1)^4 = 5^4$. Step 3: Calculate $5^4 = 5 \times 5 \times 5 \times 5 = 625$.
Coding-Decoding: If the word 'SMART' is coded as 'TLBQU' in an alternating shift pattern language ($+1, -1$), how will the word 'PRIME' be coded?
कोडिंग-डिकोडिंग: यदि एक वैकल्पिक शिफ्ट पैटर्न भाषा ($+1, -1$) में 'SMART' शब्द को 'TLBQU' कोडित किया जाता है, तो 'PRIME' शब्द को कैसे कोडित किया जाएगा?
(A) QQJLD
(B) QSJLD
(C) QQKMD
(D) QRIFD
✅ Answer & Explanation
Sahi jawab: A) QQJLDExplanation: Step 1: Analyze 'SMART' -> 'TLBQU': S(+1)->T, M(-1)->L, A(+1)->B, R(-1)->Q, T(+1)->U. Step 2: Apply this pattern to 'PRIME': P(+1)->Q, R(-1)->Q, I(+1)->J, M(-1)->L, E(+1)->D. Step 3: Combine them to get 'QQJLD'.
Classification: Find the odd letter group out from the given choices based on uniform letter gaps.
वर्गीकरण: समान अक्षरों के अंतराल के आधार पर दिए गए विकल्पों में से विषम अक्षर समूह ज्ञात कीजिए।
(A) HJMN
(B) LNPR
(C) TVXZ
(D) HJLN
✅ Answer & Explanation
Sahi jawab: A) HJMNExplanation: Step 1: Check the gaps in each group: L(+2)->N(+2)->P(+2)->R, T(+2)->V(+2)->X(+2)->Z, H(+2)->J(+2)->L(+2)->N. Step 2: Check 'HJMN': H(+2)->J(+3)->M(+1)->N. Step 3: 'HJMN' does not follow the uniform +2 step progression, so it is the odd one out.
Number Series: Complete the missing term in the sequence: 1, 2, 6, 15, 31, ?.
संख्या शृंखला: अनुक्रम में लुप्त पद को पूरा कीजिए: 1, 2, 6, 15, 31, ?.
✅ Answer & Explanation
Sahi jawab: A) 56Explanation: Step 1: Find the difference between consecutive terms: $2-1=1$, $6-2=4$, $15-6=9$, $31-15=16$. Step 2: Notice that the differences are perfect squares: $1^2, 2^2, 3^2, 4^2$. Step 3: The next difference must be $5^2 = 25$. Next term = $31 + 25 = 56$.
Letter Series: Identify the next logical term in the alphabet sequence: Z, W, S, N, H, ?.
अक्षर शृंखला: वर्णमाला अनुक्रम में अगले तार्किक पद की पहचान कीजिए: Z, W, S, N, H, ?.
✅ Answer & Explanation
Sahi jawab: A) AExplanation: Step 1: Note the positional values: Z(26), W(23), S(19), N(14), H(8). Step 2: Check the decreasing gaps: $26-3=23$, $23-4=19$, $19-5=14$, $14-6=8$. Step 3: The next gap must be -7. Position = $8 - 7 = 1$, which corresponds to 'A'.
Blood Relations: If 'A + B' means 'A is the father of B' and 'A - B' means 'A is the sister of B', then in the expression 'P + Q - R', how is P related to R?
रक्त संबंध: यदि 'A + B' का अर्थ 'A, B का पिता है' और 'A - B' का अर्थ 'A, B की बहन है' है, तो व्यंजक 'P + Q - R' में, P का R से क्या संबंध है?
(A) Father
(B) Uncle
(C) Grandfather
(D) Brother
✅ Answer & Explanation
Sahi jawab: A) FatherExplanation: Step 1: From 'Q - R', Q is the sister of R. Step 2: From 'P + Q', P is the father of Q. Step 3: Since Q is R's sister and P is Q's father, P must be the father of R as well.
Direction Sense Test: Starting from a fixed point, a man walks 10 meters East, turns left and walks 5 meters, then turns left again and walks 10 meters. How far is he from his starting point?
दिशा परीक्षण: एक निश्चित बिंदु से शुरू करके, एक व्यक्ति 10 मीटर पूर्व की ओर चलता है, बाईं ओर मुड़ता है और 5 मीटर चलता है, फिर से बाईं ओर मुड़ता है और 10 मीटर चलता है। वह अपने प्रारंभिक बिंदु से कितनी दूरी पर है?
(A) 5 meters
(B) 10 meters
(C) 15 meters
(D) 0 meters
✅ Answer & Explanation
Sahi jawab: A) 5 metersExplanation: Step 1: Moves East by 10m. Turns left (North) by 5m. Step 2: Turns left again (West) by 10m. Step 3: The East and West movements of 10m cancel each other out, leaving a net displacement of 5 meters North from the start.

✅ Answer & Explanation
Sahi jawab: A) 1Explanation: Step 1: Count intervals between characters forward and backward. Step 2: Look at pair P and R: P(16), Q(17), R(18). In the word, P and R have exactly one letter 'U' between them. Step 3: No other matching pairs exist. Total valid pair count is 1.
Ranking and Ordering: In a row of students, Amit is 11th from the left end and Deepak is 9th from the right end. If they interchange their positions, Amit becomes 18th from the left end. Find the total number of students in the row.
क्रम और रैंकिंग: छात्रों की एक कतार में, अमित बाएं छोर से 11वें स्थान पर है और दीपक दाएं छोर से 9वें स्थान पर है। यदि वे अपने स्थानों को आपस में बदलते हैं, तो अमित बाएं छोर से 18वें स्थान पर हो जाता है। कतार में छात्रों की कुल संख्या ज्ञात कीजिए।
✅ Answer & Explanation
Sahi jawab: A) 26Explanation: Step 1: After interchanging, Amit is at Deepak's original position, which is known to be 9th from the right end. Step 2: Amit's new position from the left end is given as 18th. Step 3: Total number of students = $\text{Left position} + \text{Right position} - 1 = 18 + 9 - 1 = 26$.
Syllogism: Statements: (I) Some apples are red. (II) All red items are sweet. Conclusions: (1) Some apples are sweet. (2) All sweet items are red.
न्याय निगमन (सिलोगिज़्म): कथन: (I) कुछ सेब लाल हैं। (II) सभी लाल वस्तुएं मीठी हैं। निष्कर्ष: (1) कुछ सेब मीठे हैं। (2) सभी मीठी वस्तुएं लाल हैं।
(A) Only conclusion (1) follows
(B) Only conclusion (2) follows
(C) Both follow
(D) Neither follows
✅ Answer & Explanation
Sahi jawab: A) Only conclusion (1) followsExplanation: Step 1: Some apples overlap with red. Since all red items are inside sweet, that overlapping part of apples is also sweet. Hence, conclusion 1 follows. Step 2: Sweet is the larger outer circle, so all sweet items being red is not a necessary conclusion. Only 1 follows.
Seating Arrangement: Four girls A, B, C, and D are sitting around a square table facing the center. A is sitting to the immediate left of B. C is sitting to the immediate right of D. If B is facing North, which direction is C facing?
बैठक व्यवस्था: चार लड़कियां A, B, C, और D एक वर्गाकार मेज के चारों ओर केंद्र की ओर मुख करके बैठी हैं। A, B के ठीक बाईं ओर बैठी है। C, D के ठीक बाईं ओर (या दाईं ओर) बैठी है। यदि B का मुख उत्तर की ओर है, तो C का मुख किस दिशा में है?
(A) West
(B) South
(C) East
(D) North
✅ Answer & Explanation
Sahi jawab: A) WestExplanation: Step 1: B is on the South side facing North. Immediate left of B (facing center) is the East side. So A is on the East side facing West. Step 2: The remaining spots are North and West sides for C and D. C is to the right of D, which places D on the North side facing South and C on the West side facing East. Step 3: Therefore, C is facing East.
Dice Puzzle: A standard dice displays numbers 1 to 6. If faces 1, 2, and 3 are adjacent to face 4, which number must be on the face opposite to 4?
पासा पहेली: एक मानक पासे पर 1 से 6 तक की संख्याएं प्रदर्शित होती हैं। यदि फलक 1, 2, और 3 फलक 4 के आसन्न हैं, तो फलक 4 के विपरीत कौन सी संख्या होनी चाहिए?
(A) 5 or 6
(B) 1
(C) 2
(D) 3
✅ Answer & Explanation
Sahi jawab: A) 5 or 6Explanation: Step 1: In a closed standard dice cube framework, a face can have 4 adjacent faces and 1 opposite face. Step 2: Since 1, 2, 3 are adjacent, the opposite must be among the remaining unlisted faces (5 or 6). Step 3: Without extra configuration views, it is either 5 or 6.
Analogy: Complete the relation sequence: $7 : 56 :: 9 : ?$.
सादृश्यता: संबंध अनुक्रम को पूरा कीजिए: $7 : 56 :: 9 : ?$.
