Question

In which of the following towns does the LMT (Local Meridian Time) show the greatest deviation from the IST (Indian Standard Time)?

  1. A. Kolkata
  2. B. Cochin
  3. C. Mumbai
  4. D. Kohima (Correct answer)

Correct Answer

Option D — Kohima

Detailed Solution & Explanation

The correct answer is Kohima.

Key Points

  • IST is based on 82.5°E. Kohima (Nagaland) is at ~94°E — deviation ≈ +46 min (ahead of IST).
  • Mumbai (~72.8°E) deviates ~39 min behind.
  • Kohima has the greatest absolute deviation from IST among the given options.

Additional Information

  • IST is fixed on 82°30'E, the longitude passing through Mirzapur in Uttar Pradesh; every 1° of longitude corresponds to 4 minutes of time.
  • Kohima lies near 94°E, roughly 11.5° east of the IST meridian, so local time runs about 46 minutes ahead — the reason the north-east sees sunrise so much earlier.
  • This gap drives the recurring public debate about a separate time zone for the north-eastern states.
