RRB NTPC Graduate Level (27th March 2026 Shift 2) — RRB NTPC 2025

• Key Fact: Dholavira, an ancient Harappan archaeological site, is located on Khadir Bet island in the Kutch Desert Wildlife Sanctuary in the Great Rann of Kutch, which is in the Kutch district of Gujarat.

• Supporting Detail: It was discovered in 1968 by archaeologist Jagat Pati Joshi and is known for its unique water management system and extensive stone architecture.

• Related Concept: It became the 40th Indian site to be inscribed on the UNESCO World Heritage List in 2021.

• Why others wrong: Patan is famous for Rani ki Vav (another World Heritage Site). Banaskantha and Jamnagar do not host major excavated Harappan cities of this scale.

• Exam Trick: Remember 'Kutch' -> 'Khadir Bet' -> 'Dholavira' (White well).

• Additional Info: Unlike other Harappan cities which were divided into two parts (Citadel and Lower Town), Dholavira was divided into three distinct parts (Citadel, Middle Town, and Lower Town).

• Given conditions: CAST = 3519. SIDE = 8645.

• Deduction process:
Step 1: Identify the letters that are common to both words 'CAST' and 'SIDE'.
Comparing C, A, S, T with S, I, D, E, the only common letter is 'S'.
Step 2: Identify the digits that are common to both codes '3519' and '8645'.
Comparing 3, 5, 1, 9 with 8, 6, 4, 5, the only common digit is '5'.
Step 3: Since 'S' is the only common letter and '5' is the only common digit, the code for 'S' must be '5'.

• Additional Concept: In scrambling-based substitution coding, the order of numbers does not match the order of letters. Always look for intersections across multiple words.

• Exam Trick: Visually scan for the single overlapping element. S is in both. 5 is in both. S=5. It takes less than 5 seconds.

• Final Answer: 5

• Given: Assignment Score $x_1 = 75$, Weight $w_1 = 40\%$. Exam Score $x_2 = 85$, Weight $w_2 = 60\%$.

• Basic Method (Solution):
Step 1: The formula for the weighted arithmetic mean is $\frac{w_1 x_1 + w_2 x_2}{w_1 + w_2}$.
Step 2: Substitute the given values into the formula.
Numerator $= (40 \times 75) + (60 \times 85)$.
$40 \times 75 = 3000$.
$60 \times 85 = 5100$.
Total Sum $= 3000 + 5100 = 8100$.
Step 3: The sum of the weights is $40 + 60 = 100$.
Step 4: Weighted Mean $= \frac{8100}{100} = 81$.

• Shortcut Method: Convert weights to simpler ratios. $40\%$ to $60\%$ is a $2:3$ ratio. Using the deviation method from a base of 75: the second score is $+10$ above the base. This $+10$ is weighted by 3 parts out of total 5 parts. Average increase $= 10 \times \frac{3}{5} = 6$. So, weighted mean $= 75 + 6 = 81$.

• Final Answer: 81

• Given conditions: Series is MPW 30, HKR 25, CFM 20, XAH 15, ?

• Deduction process:
Step 1: Analyze the letters in the first position of each cluster.
M(13) $\rightarrow -5 \rightarrow$ H(8) $\rightarrow -5 \rightarrow$ C(3) $\rightarrow -5 \rightarrow$ X(24) $\rightarrow -5 \rightarrow$ S(19)
(Note: C(3) $- 5 = -2$, which maps to $26 - 2 = 24$ = X).
Step 2: Analyze the letters in the second position.
P(16) $\rightarrow -5 \rightarrow$ K(11) $\rightarrow -5 \rightarrow$ F(6) $\rightarrow -5 \rightarrow$ A(1) $\rightarrow -5 \rightarrow$ V(22)
(Note: A(1) $- 5 = -4$, which maps to $26 - 4 = 22$ = V).
Step 3: Analyze the letters in the third position.
W(23) $\rightarrow -5 \rightarrow$ R(18) $\rightarrow -5 \rightarrow$ M(13) $\rightarrow -5 \rightarrow$ H(8) $\rightarrow -5 \rightarrow$ C(3)
So the letter part of the answer must be SVC.
Step 4: Analyze the numbers.
$30 \rightarrow -5 \rightarrow 25 \rightarrow -5 \rightarrow 20 \rightarrow -5 \rightarrow 15 \rightarrow -5 \rightarrow 10$
The number part of the answer must be 10.
Step 5: Combine them to get the final cluster: SVC 10.

• Additional Concept: The alphabet is cyclical. When a subtraction results in a value $\le 0$, simply add 26 to find the correct letter mapping (e.g., $1 - 5 = -4 \Rightarrow -4 + 26 = 22 = V$).

• Exam Trick: Just check the numbers first: 30, 25, 20, 15... the next is 10. Only option C ends with 10. You don't even need to calculate the letters! Takes 2 seconds.

• Final Answer: SVC 10

• Given conditions: Series is HAK 8, GYH 11, FWE 14, EUB 17, ?

• Deduction process:
Step 1: Analyze the letters in the first position.
H(8) $\rightarrow -1 \rightarrow$ G(7) $\rightarrow -1 \rightarrow$ F(6) $\rightarrow -1 \rightarrow$ E(5) $\rightarrow -1 \rightarrow$ D(4)
Step 2: Analyze the letters in the second position.
A(27) $\rightarrow -2 \rightarrow$ Y(25) $\rightarrow -2 \rightarrow$ W(23) $\rightarrow -2 \rightarrow$ U(21) $\rightarrow -2 \rightarrow$ S(19)
Step 3: Analyze the letters in the third position.
K(11) $\rightarrow -3 \rightarrow$ H(8) $\rightarrow -3 \rightarrow$ E(5) $\rightarrow -3 \rightarrow$ B(2) $\rightarrow -3 \rightarrow$ Y(25)
(Note: B(2) $- 3 = -1 \Rightarrow -1 + 26 = 25 = Y$).
So the letter part of the answer must be DSY.
Step 4: Analyze the numbers.
$8 \rightarrow +3 \rightarrow 11 \rightarrow +3 \rightarrow 14 \rightarrow +3 \rightarrow 17 \rightarrow +3 \rightarrow 20$
The number part of the answer must be 20.
Step 5: Combine them to get the final cluster: DSY 20.

• Additional Concept: The differences are not constant across positions. The first letter decreases by 1, the second by 2, and the third by 3. Identify each position's pattern separately.

• Exam Trick: Check the number first: $17 + 3 = 20$ (eliminates A). Check the first letter: E $- 1 = D$ (eliminates D). Check the last letter: B $- 3 = Y$ (eliminates C). DSY 20 is the exact match.

• Final Answer: DSY 20

• Key Fact: Vembanad Lake (or Vembanad Kayal) is the longest lake in India and the largest lake in the state of Kerala. It spans several districts and is located on the Malabar Coast.

• Supporting Detail: The lake is separated from the Arabian Sea by a narrow barrier island and is famously known for the Nehru Trophy Boat Race and its intricate backwater tourism.

• Related Concept: The Malabar Coast represents the southwestern coast of India, primarily covering Kerala and parts of Karnataka. The Coromandel Coast is on the southeastern side (Tamil Nadu/Andhra).

• Why others wrong: Northern Circar is the northern part of the eastern coast (Odisha/Andhra). Konkan Coast is the western coast covering Maharashtra and Goa. Coromandel is the eastern coast.

• Exam Trick: 'Kerala' = 'Backwaters' (Kayals) = 'Vembanad' = 'Malabar Coast'.

• Additional Info: The lake is recognized as a Wetland of International Importance under the Ramsar Convention.

• Given conditions: 6 floors (1 to 6). C is on an even floor (2, 4) not 6. F + C = 7. B is immediately above E. C + D = 3.

• Deduction process:
Step 1: Focus on C. C must be on floor 2 or 4. Also, C + D = 3. Since floors are positive integers, the only way to sum to 3 is $1 + 2$. Therefore, the floors for C and D must be 1 and 2. Since C is on an even floor, C MUST be 2, and D MUST be 1.
Step 2: Use the condition F + C = 7. We know C = 2. So, $F + 2 = 7 \Rightarrow F = 5$.
Step 3: Current known floors: D(1), C(2), F(5). The empty floors are 3, 4, and 6.
Step 4: Use the condition 'B lives immediately above E'. This requires two consecutive empty floors. The only consecutive empty floors are 3 and 4. So, E is on 3 and B is on 4.
Step 5: The only person left is A, who must occupy the remaining top floor, 6.
Final arrangement (Top to Bottom): 6-A, 5-F, 4-B, 3-E, 2-C, 1-D.
Step 6: The question asks how many people live above B (who is on floor 4). The people on floors 5 and 6 live above B. That is 2 people (F and A).

• Additional Concept: Equations like C + D = 3 with distinct positive integer variables strictly limit the values (only 1 and 2 are possible).

• Final Answer: Two

• Key Fact: The Akash Next Generation (Akash-NG) missile system successfully completed its User Evaluation Trials conducted by DRDO.

• Supporting Detail: Akash-NG is a new-generation surface-to-air missile meant for use by the Indian Air Force with the aim of intercepting high maneuvering low radar cross-section aerial threats.

• Related Concept: The original Akash missile system has been one of India's most successful indigenous defence systems, already inducted into both the Army and the Air Force, and also exported.

• Why others wrong: Astra, BrahMos, and Prithvi-II are active components of the Indian armed forces but the specific 'User Evaluation Trials' milestone in this timeframe pertains to the newly upgraded Akash-NG variant.

• Exam Trick: Remember 'NG' stands for Next Generation. When a long-standing indigenous program (like Akash) gets an 'NG' upgrade, it undergoes extensive user trials by the armed forces before final induction.

• Additional Info: The Akash-NG system incorporates an active electronically scanned array (AESA) radar.

• Key Fact: María Corina Machado, a prominent Venezuelan opposition leader, has been globally recognized (including Nobel consideration in this projected scenario) for her relentless fight against the authoritarian regime of Nicolás Maduro.

• Supporting Detail: Despite being controversially banned from running in the 2024 presidential elections, she united the opposition and advocated for democratic restoration through peaceful means.

• Related Concept: The Nobel Peace Prize is awarded annually in Oslo, Norway, to those who have "done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses".

• Why others wrong: Juan Guaidó and Leopoldo López are also notable Venezuelan opposition figures but the specific recognition for uniting the 2024/2025 democratic movement belongs to Machado. Michelle Bachelet is the former President of Chile and UN High Commissioner for Human Rights.

• Exam Trick: Associate "fearless advocacy of democracy in Venezuela" in recent years (2024-2025) heavily with the female leader "María Corina Machado" who dominated the news cycle.

• Additional Info: The Norwegian Nobel Committee awards the Peace Prize, which is the only Nobel Prize not awarded in Stockholm, Sweden.

• Key Fact: Major Rajyavardhan Singh Rathore won the silver medal in the Men's Double Trap shooting event at the 2004 Summer Olympics in Athens.

• Supporting Detail: This was a historic moment as it was India's first-ever individual Olympic silver medal post-independence.

• Related Concept: Abhinav Bindra later went one step further and won India's first individual Olympic gold medal in the 10m Air Rifle event at the 2008 Beijing Olympics.

• Why others wrong: Abhinav Bindra won gold in 2008. The other two names are fictitious or non-Olympians in this context.

• Exam Trick: Remember 'Rathore' for the 'Silver' that paved the way for Bindra's 'Gold'. Both were shooters.

• Additional Info: Rathore later entered politics and served as the Minister of State for Youth Affairs and Sports in the Government of India.
