Question: 1
The maximum number of trees has been affected by the project
The correct option is (D): Chamera-I (HP) From the table we can see that: The maximum number of trees affected are 40,000 and is caused by Chamera-I (HP).

Question: 2
Out of the given projects, the minimum forest area involved has been in respect of
The correct option is (B): Dulhasti (J and K) Explanation:To find the case with the maximum density of trees planted, we need to calculate the density of trees for each project by dividing the number of trees planted by the area afforested (in hectares). The project with the highest density will be the answer. Let's calculate the density for each project: 1. Chamera-I (HP): \( \text{Density} = \frac{39,81,186}{2000} = 1990.59 \text{ trees per hectare} \) 2. Dulhasti (J&K): \( \text{Density} = \frac{7,85,673}{18} = 43,648.5 \text{ trees per hectare} \) 3. Rangit (Sikkim): \( \text{Density} = \frac{3,32,000}{38} = 8,736.84 \text{ trees per hectare} \) Clearly, the Dulhasti (J&K) project has the highest density of trees planted.

Question: 4
Out of the given projects, maximum forest area involved is in the State of
The correct option is (A): Himachal Pradesh Explanation: To determine the state with the maximum forest area involved, we can refer to the forest area data provided in the table. Himachal Pradesh: - Chanera-I: 982.50 ha - Chamera-II: 78.78 ha - Total for Himachal Pradesh = \(982.50 + 78.78 = 1,061.28\) ha Jammu & Kashmir: - Dulhasti: 1.1 ha - Uri: 54.71 ha - Total for Jammu & Kashmir = \(1.1 + 54.71 = 55.81\) ha Sikkim: - Rangit: 34.60 ha Uttaranchal: - Tanakpur: 293.35 ha - Dhauliganga-I: 138.60 ha - Total for Uttaranchal = \(293.35 + 138.60 = 431.95\) ha The maximum forest area involved is in Himachal Pradesh with 1,061.28 hectares.
