Correct Answer:
Option D —
Kohima
• IST Reference: Indian Standard Time (IST) is calculated based on the 82.5° E longitude, which passes through Mirzapur (near Allahabad). This is the "mean" time for the entire country.
• The further a town is located (either East or West) from the 82.5° E meridian, the greater its Local Meridian Time (LMT) will deviate from the IST.
• Geographical Analysis:
o Kolkata: Approximately 88° E (Difference: ~5.5°)
o Cochin: Approximately 76° E (Difference: ~6.5°)
o Mumbai: Approximately 72° E (Difference: ~10.5°)
o Kohima: Approximately 94° E (Difference: ~11.5°)
• Conclusion: Since Kohima is the easternmost point among the given options, it has the highest longitudinal displacement from the standard meridian, resulting in the greatest time deviation (roughly 46 minutes ahead of the 82.5° E mean).
