3. Worked Example
Problem:
Which Indian state has the highest forest cover (in km²) as per the latest Forest Survey?
Solution Steps
- Identify the source – Forest Survey of India (2023 report).
- List top 5 states by forest area (approximate values):
Rank State Forest Area (km²) 1 Arunachal Pradesh 95,000 2 Mizoram 41,000 3 Meghalaya 32,000 4 Assam 30,000 5 Sikkim 12,000 - Answer – Arunachal Pradesh has the largest forest cover.
Take‑away – In exam settings, always cross‑check the latest FAO/Forest Survey data; the numbers can change with new surveys.
