Q50. Which state among the following is crossed by the Tropic of Cancer?
[UPSC NDA-II (2007)]
(A) Assam
(B) Manipur
(C) Mizoram
(D) Nagaland
Answer: (C) Mizoram
Explanation: Mizoram is one of two northeastern Indian states crossed by the Tropic of Cancer; Tripura is the other. Assam, Manipur and Nagaland lie north of this latitude. The question examines regional positioning rather than state capitals.
Q49. Which Indian state shares the longest boundary with Myanmar among those listed?
[RAS/RTS Preliminary Examination (2006–07)]
(A) Manipur
(B) Arunachal Pradesh
(C) Mizoram
(D) Nagaland
Answer: (B) Arunachal Pradesh
Explanation: The historical examination key identifies Arunachal Pradesh as having the longest India–Myanmar boundary among these states. The other border states are Nagaland, Manipur and Mizoram. Figures for boundary segments can vary with measurement conventions.
Q48. Which is the largest Indian district by geographical area in the given alternatives?
[WBCS Preliminary Examination (2007)]
(A) Bastar
(B) Kachchh
(C) Leh–Ladakh
(D) Burdwan
Answer: (B) Kachchh
Explanation: Kachchh district in Gujarat is exceptionally large, exceeding 45,000 square kilometres. It occupies the western edge of the Indian mainland, adjoining Pakistan and the Arabian Sea. District boundaries should be interpreted in their examination-period context.
Q47. Which Indian state does not share a boundary with Bangladesh?
[Uttarakhand UDA/LDA Main Examination (2007)]
(A) Meghalaya
(B) Tripura
(C) Manipur
(D) Mizoram

Explanation: Manipur has an international border with Myanmar, not Bangladesh. Meghalaya, Tripura and Mizoram all touch Bangladesh. This distinction matters because several northeastern states lie close together but have different neighbouring countries.
Q46. Which of these statements about India are true?
1. India ranks fifth by area.
2. India occupies about 2.4% of world land area.
3. All of India is tropical.
4. IST uses 82°30′ E.
[UPPCS Main Examination (2006)]
(A) 1 and 2
(B) 2 and 3
(C) 1 and 3
(D) 2 and 4
Answer: (D) 2 and 4
Explanation: India is seventh, not fifth, in world area. It accounts for about 2.4% of the world’s land area, and the standard longitude is 82°30′ E. Northern India extends beyond the tropics, making statement three incorrect.
Q45. In June, which city among the following experiences the longest daylight?
[Uttarakhand PCS Main Examination (2006)]
(A) Hyderabad
(B) Chennai
(C) Bhopal
(D) Delhi
Answer: (D) Delhi
Explanation: Near the June solstice, daylight generally increases northward across these Northern Hemisphere locations. Delhi is the northernmost of the listed cities and therefore has the longest daytime. This differs from clock time, which remains uniform within India.

[MPPSC Preliminary Examination (2006)]
(A) United States and Canada
(B) India and Pakistan
(C) India and China
(D) Russia and Finland

Q42. The historical Durand Line marks a boundary associated with which neighbour of British India?
[UP UDA/LDA Preliminary Examination (2006)]
(A) Afghanistan
(B) Myanmar
(C) Nepal
(D) Tibet
Answer: (A) Afghanistan

Its inclusion in old examination questions reflects the historical British-Indian frontier, not a currently administered India–Afghanistan line.
