The 1ST meridian 821/2°E passes through a number of States in India. Which one of the following sets of States is correct in this respect?
Explanation
The Standard Meridian of India is located at 82°30' E (or 82.5° E) longitude [2]. This meridian is used to determine Indian Standard Time (IST), which is 5 hours and 30 minutes ahead of Greenwich Mean Time [2]. Geographically, this line passes through five Indian states: Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha, and Andhra Pradesh [1]. Specifically, it is often cited as passing through Mirzapur near Prayagraj (Allahabad) in Uttar Pradesh [1]. Among the given options, set 4 correctly identifies four of these five states: Uttar Pradesh, Odisha, Andhra Pradesh, and Chhattisgarh. Other options are incorrect because they include states like Uttarakhand or Jharkhand, which the 82.5° E meridian does not traverse. While one source mentions the line running through Ranchi, Jharkhand, the consensus in standard geographical texts and official references confirms the five-state path excluding Jharkhand [2].
