History, Geography, Culture & Miscellaneous Current Affairs: Solved Questions with Step-by-Step Explanations (2 Problems)

Question 1 · General Knowledge (GK) NAT

Consider the following historic capitals of Indian kingdoms: (1) Pataliputra, (2) Kannauj, (3) Rajahmundry, (4) Karur.

A scholar assigns a numeric rank to each capital based on its geographic latitude from North to South (Rank 1 being the northernmost, Rank 4 being the southernmost).

The scholar then defines a historical time window starting from Year $X = 1800 + (Rank of Kannauj \times 24)$ and ending at Year $Y = 1900 + (Rank of Rajahmundry \times 4)$ .

According to the strict Gregorian calendar rules, how many leap years fall within this inclusive time window from Year $X$ to Year $Y$ ?

Correct Answer:

Step-by-Step Solution

Key idea: This is a language_to_math synthesis question requiring you to translate geographic rankings into a mathematical calendar boundary problem.

Step 1: Determine the North-to-South geographic ranks of the capitals.

Kannauj (Uttar Pradesh) $\approx 27. 0^{\circ}$ N $\to$ Rank 1
Pataliputra (Bihar) $\approx 25. 6^{\circ}$ N $\to$ Rank 2
Rajahmundry (Andhra Pradesh) $\approx 17. 0^{\circ}$ N $\to$ Rank 3
Karur (Tamil Nadu) $\approx 10. 9^{\circ}$ N $\to$ Rank 4

Step 2: Calculate Year $X$ and Year $Y$ .

$X = 1800 + (1 \times 24) = 1824$
$Y = 1900 + (3 \times 4) = 1912$

Step 3: Count the leap years in the inclusive range [1824, 1912] using Gregorian rules.

1824 to 1896: These are standard years divisible by 4. Count = $(1896 - 1824) /4 + 1 = 19$ leap years.
1900: This is a century year. Since $1900$ is not divisible by $400$ , it is NOT a leap year. Count = $0$ .
1904 to 1912: Standard leap years. Count = $3$ (1904, 1908, 1912).

Step 4: Sum the counts. Total = $19 + 0 + 3 = 22$ .

Answer: 22

Question 2 · General Knowledge (GK) MCQ

Consider the following international organizations and their respective headquarters:

New Development Bank (NDB)
International Solar Alliance (ISA)
SAARC Secretariat
BIMSTEC Secretariat
Asian Development Bank (ADB)

Arrange the host cities of these organizations in descending order of their geographic latitude (from North to South).

A.
Gurugram - Shanghai - Kathmandu - Dhaka - Manila
B.
Shanghai - Gurugram - Kathmandu - Dhaka - Manila
C.
Shanghai - Kathmandu - Gurugram - Dhaka - Manila
D.
Gurugram - Kathmandu - Shanghai - Manila - Dhaka

Correct Answer:

Step-by-Step Solution

Key idea: This is an order_ranking question testing the precise latitudinal positioning of global and regional institutional capitals.

Step 1: Identify the host cities.

NDB is headquartered in Shanghai, China.
ISA is headquartered in Gurugram (Delhi NCR), India.
SAARC Secretariat is in Kathmandu, Nepal.
BIMSTEC Secretariat is in Dhaka, Bangladesh.
ADB is headquartered in Manila, Philippines.

Step 2: Determine the latitudes.

Shanghai is at approximately 31.2° N.
Gurugram (Delhi NCR) is at approximately 28.4° N.
Kathmandu is at approximately 27.7° N.
Dhaka is at approximately 23.8° N.
Manila is at approximately 14.5° N.

Step 3: A common trap is assuming Kathmandu is further north than Gurugram because it is in the Himalayas. However, the Kathmandu Valley lies south of the Delhi NCR latitude.

Step 4: The correct North-to-South order is Shanghai $\to$ Gurugram $\to$ Kathmandu $\to$ Dhaka $\to$ Manila.

Answer: Shanghai - Gurugram - Kathmandu - Dhaka - Manila.
