Explanation:
India is east of Greenwich and ahead by 5 hours and 30 minutes:
- The Earth is divided into 24 time zones, each 15 degrees of longitude apart.
- Greenwich, in London, is the starting point for calculating time zones (0 degrees longitude).
- India is located to the east of Greenwich, so the time in India is ahead of London.
- Since each time zone represents 15 degrees of longitude, India being 82.5 degrees east of Greenwich is 5 hours and 30 minutes ahead of London.
- This is why when it is 12 noon in London, it is 5.30 p.m. in India.

India is located east of the Prime Meridian (Greenwich) at 82°30'E. The Earth rotates 360° in about 24 hours, meaning it rotates 15° per hour. Therefore, India, being approximately 82.5° east of Greenwich, is ahead by about 5 hours and 30 minutes (82.5° / 15° per hour). This time difference explains why it is 5.30 p.m. in India when it is 12 noon in London. Interestingly, different countries adopt their standard time based on their longitudinal position relative to Greenwich.
