Indian Geography (Part-I)

31. If it is 10.00 a.m. IST, then what would be the local time at Shillong at 92° E longitude? [I.A.S. (Pre) 1999]

(a) 9.38 a.m.
(b) 10.38 a.m.
(c) 10.22 a.m.
(d) 9.22 a.m.

Correct Answer: (b) 10.38 a.m.

Solution:Indian Standard Time is calculated on the basis of 82.5° E longitude. The difference between the longitude of Shillong and the Indian Standard Time is 92° - 82.5° = 9.5°. As we know that the difference of 1 longitude is equals to 4 minutes. So the difference in time between them is 9.5 x 4 = 38 minutes. So, if a watch indicates 10:00 a.m. on IST, then 10:38 a.m. would be the local time at Shillong. Thus the correct answer is option (b).

32. When it is noon at IST meridian, what would be the local time at 120° East longitude – [U.P.P.C.S. (Pre) 2001]

(a) 09.30
(b) 14.30
(c) 17.30
(d) 20.00

Correct Answer: (b) 14.30

Solution:The longitudinal difference between the Indian Standard Time and 120° E longitude is 120° - 82°30' = 37°30'. Since the difference of 1 longitude is equal to 4 minutes. So the difference in time between them is 37°30' x 4 = 150 minutes (means 2 hours, 30 minutes). Thus, if it is noon at IST meridian, then the local time at 120° East longitude is 12:00 + 2:30 = 14:30.

33. The Indian Standard Time Meridian does not pass through – [U.P.P.C.S. (Mains) 2010]

(c) Patna

Correct Answer: (d) Allahabad

Solution:Indian Standard Time is calculated on the basis of 82° 30' E longitude. This Meridian passes through Mirzapur district (Near Prayagraj) in the state of Uttar Pradesh. It also passes through Jagdalpur of Chhattisgarh. The Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes.

35. Which of the following longitudes is known as “Standard Meridian” in India? [U.P.P.C.S. (Pre) 2013, U.P. Lower Sub. (Pre) 2013]

(a) 87° 30' E
(b) 85° 30' E
(c) 84° 30' E
(d) 82° 30' E

Correct Answer: (d) 82° 30' E

Solution:Indian Standard Time is calculated on the basis of 82° 30' E longitude. This Meridian passes through Mirzapur district (Near Prayagraj) in the state of Uttar Pradesh. It also passes through Jagdalpur of Chhattisgarh. The Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes.

36. The Indian Standard Time is taken from which of the following city? [U.P.P.C.S. (Pre) 1993]

(a) Allahabad (Naini)
(b) Lucknow
(c) Meerut
(d) Muzaffarnagar

Correct Answer: (a) Allahabad (Naini)

Solution:Indian Standard Time is calculated on the basis of 82° 30' E longitude. This Meridian passes through Mirzapur district (Near Prayagraj) in the state of Uttar Pradesh. It also passes through Jagdalpur of Chhattisgarh. The Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes.

37. How much is the difference between Indian Standard Time (I.S.T.) and Greenwich Mean Time (G.M.T.)? [Jharkhand P.C.S. (Pre) 2010, 45th B.P.S.C. (Pre) 2001, Jharkhand P.C.S. (Pre) 2003]

(a) + 4 ½ hours
(b) + 5 ½ hours
(c) – 5 hours
(d) – 4 ½ hours

Correct Answer: (b) + 5 ½ hours

Solution:Indian Standard Time is calculated on the basis of 82° 30' E longitude. This Meridian passes through Mirzapur district (Near Prayagraj) in the state of Uttar Pradesh. It also passes through Jagdalpur of Chhattisgarh. The Indian Standard Time is ahead of Greenwich Mean Time by 5 hours and 30 minutes.

38. If the Sun rises at TIRAP in Arunachal Pradesh at 5.00 am (IST) then what time (IST) will the Sun rise in Kandla in Gujarat? [U.P.P.C.S (Pre) 2010]

(a) About 5.30 a.m.
(b) About 6.00 a.m.
(c) About 7.00 a.m.
(d) About 7.30 a.m.

Correct Answer: (c) About 7.00 a.m.

Solution:There is a difference of about 2 hours between Kandla (Gujarat) and Tirap (Arunachal Pradesh) due to the longitudinal position of both the cities. Thus, if the Sun rises at Tirap (95° 31') in Arunachal Pradesh at 5:00 a.m. (IST) then the Sun will rise at 7:00 a.m. in Kandla (70° 11').

39. Among the following cities, which one lies on a longitude closest to that of Delhi? [I.A.S. (Pre), 2018]

(a) Bengaluru
(b) Hyderabad
(c) Nagpur
(d) Pune

Correct Answer: (a) Bengaluru

Solution:The longitudinal extent of Delhi is between 76°50' East to 77°22' East. That city will be located on the longitude nearest to Delhi, which will have the least longitude difference from Delhi. The longitudinal extent of the cities given in the question is as follows –

City	Longitudinal extent
Bengaluru	77°19' East to 77°50' East
Hyderabad	78°23' East to 78°68' East
Nagpur	78°15' East to 79°40' East
Pune	73°19' East to 75°10' East

Among the given option, Bengaluru will be located on the closest longitude to Delhi, because the longitudinal difference between Delhi and Bengaluru is the most. Hence the option (a) is the correct answer.

40. On which plateau, the Tropic of Cancer and the Indian Standard Time Line intersect each other? [69th B.P.S.C. (Pre), 2023]

(a) Bundelkhand
(b) Baghelkhand
(c) Malwa
(d) None of the above

Correct Answer: (b) Baghelkhand

Solution:Tropic of Cancer is 23.5°N and Indian standard date line is 82.5°E. Significantly, Tropic of Cancer passes through eight states - Rajasthan, Gujarat, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram while Indian standard time line passes through five states - Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha and Andhra Pradesh. They both intersect at Koria district in Chhattisgarh. Korea district lies in Baghelkhand Plateau.
