[RRB NTPC UG CBT-I (12 August 2025)]
(A) Sri Lanka
(B) Afghanistan
(C) China
(D) Myanmar
Answer: (A) Sri Lanka
Explanation: Sri Lanka is separated from India by the Palk Strait and Gulf of Mannar and has no land boundary with it. India’s official territorial descriptions include borders with China, Myanmar and, by claimed territory, Afghanistan.
Q139. Tropic of Cancer passes through which of the following countries?
[Himachal Pradesh High Court Clerk (6 July 2025)]
(A) India
(B) Brazil
(C) Australia
(D) None of these
Answer: (A) India
Explanation: The Tropic of Cancer is the parallel around 23°30′ N and crosses the Indian subcontinent. Brazil and Australia lie in the Southern Hemisphere tropics and are associated instead with the Tropic of Capricorn, not the Tropic of Cancer.
Q138. Indira Point, the southernmost tip of India, is located on which island?
[RRB NTPC Graduate CBT-I (17 June 2025)]
(A) Little Nicobar
(B) Nancowry
(C) Great Nicobar
(D) Car Nicobar
Answer: (C) Great Nicobar
Explanation: Indira Point occupies the southern tip of Great Nicobar Island. It is considerably farther south than the Indian mainland and lies near Indonesian waters. Kanyakumari, often confused with it, is only the southernmost mainland point.
Q137. Which of the following countries is separated from India by a maritime boundary only?
[RRB NTPC Graduate CBT-I (9 June 2025)]
(A) Myanmar
(B) Bhutan
(C) Nepal
(D) Maldives
Answer: (D) Maldives
Explanation: The Maldives lies southwest of India in the Indian Ocean, so India and Maldives are maritime neighbours without a land frontier. Myanmar has a land border with northeastern India, while Bhutan and Nepal are entirely land-border neighbours.
Q136. The India–Bhutan boundary is primarily defined by which of these?
[RRB NTPC Graduate CBT-I (6 June 2025)]
(A) Desert regions
(B) Mountains and treaties
(C) Trade posts alone
(D) Border fencing alone
Answer: (B) Mountains and treaties
Explanation: The India–Bhutan frontier runs through the eastern Himalayan foothill region and follows historically agreed boundary arrangements. It is not a desert boundary. Trading points and fencing cannot independently define the international boundary between the countries.
Q135. In which of the following districts of Madhya Pradesh does the Tropic of Cancer not pass?
[MPPSC Assistant Professor General Studies (1 June 2025)]
(A) Vidisha
(B) Indore
(C) Ujjain
(D) Bhopal
Answer: (B) Indore
Explanation: The Tropic of Cancer passes through the central belt of Madhya Pradesh, including the Bhopal, Vidisha and Ujjain regions. Indore lies south of this latitude. Its position on the map is therefore the deciding factor.
Q134. Consider the following lines of longitude and latitude:
1. Prime Meridian
2. Tropic of Cancer
3. Equator.
Which of the above lines is/are a Great Circle?
[UPSC NDA General Ability (13 April 2025)]
(A) 1, 2 and 3
(B) 1 and 2 only
(C) 1 and 3 only
(D) 3 only
Answer: (D) 3 only
Explanation: A great circle divides a sphere into two equal hemispheres. Among the listed individual lines, only the Equator forms a complete great circle. The Prime Meridian is a semicircle unless combined with its opposite meridian; the Tropic of Cancer is smaller.
Q133. The Tropic of Cancer passes through middle India from the _____.
[APSSB Multi-Tasking Staff (23 February 2025)]
(A) Gulf of Khambhat to Sikkim
(B) Rann of Kachchh to Mizoram
(C) Mumbai to Mizoram
(D) None of these
Answer: (B) Rann of Kachchh to Mizoram
Explanation: The Tropic of Cancer enters India through Gujarat in the west and continues across central and eastern states before reaching Mizoram. The Rann of Kachchh–Mizoram description represents this west-to-east route better than the other alternatives.
Q132. Which of the following factors does NOT contribute substantially to India’s climatic diversity?
[SSC MTS (22 October 2024)]
(A) Longitudinal extent
(B) Latitudinal extent
(C) Topography
(D) Vegetation
Answer: (A) Longitudinal extent
Explanation: Latitude governs the angle of incoming solar radiation, while altitude and relief strongly affect Indian climate. Longitudinal extent chiefly creates local-time differences across the country. It is generally not treated as a principal driver of India’s broad climatic diversity in this question.
Q131. Which is the Standard Meridian of India?
[SSC CHSL Tier-I (5 July 2024)]
(A) 83°30′ E
(B) 82°30′ E
(C) 81°30′ E
(D) 84°40′ E
Answer: (B) 82°30′ E
Explanation: The meridian at 82°30′ east longitude is the reference for Indian Standard Time. This centrally positioned longitude enables the entire country to use one clock time despite an east–west spread of nearly 30 degrees of longitude.
