NHPC has undertaken massive afforestation, which is an effective tool in arresting sail erosion and enrichment of environment. The details are as under
SI. | Name of | Forest Area | Area | No. of trees | No. of trees |
| 1. | Chanera-I (HP) | 982.50 | 2000 | 40,000 | 39,81,186 |
| 2. | Dulhasti (J&K) | 1.1 | 18 | 700 | 7,85,673 |
| 3. | Rangit (Sikkim) | 34.60 | 38 | 5,000 | 3,32,000 |
| 4. | Tanakpur (Uttaranchal) | 293.35 | 350 | 17,368 | 6,66,165 |
| 5. | Uri (J&K) | 54.71 | 62.70 | 4,000 | 3,21,000 |
| 6. | Dhauliganga-I (Uttaranchal) | 138.60 | 140.73 | 1,517 | 2,87,887 |
| 7. | Chamera-II (H.P) | 78.78 | 172.58 | 1,380 | 2,30,000 |
| Total | 69,965 | 66,03,911 |
The maximum number of trees has been affected by the project
- Chamera-ll (HP)
- Tanakpur
- Uri (J andK)
- Chamera-I (HP)
The Correct Option is D
Solution and Explanation
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).
Out of the given projects, the minimum forest area involved has been in respect of
- Dulhasti (J and K)
- Uri (J and K)
- Rangit (Sikkim)
- Chamera-ll (HP)
The Correct Option is A
Solution and Explanation
The correct option is (A): Dulhasti (J and K)
Dulhasti (J&K) has the smallest forest area, which is equal to 1.1 hectares.
Assuring that the trees have been planted on more or less even distribution, the density of the trees planted has been maximum in the case of
- Chamera-1 (HP)
- Dulhasti (J and K)
- Rangit (Sikkim)
- None of the above
The Correct Option is B
Solution and Explanation
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.
Out of the given projects, maximum forest area involved is in the State of
- Himachal Pradesh
- Jammu and Kashmir
- Sikkim
- Uttranchal
The Correct Option is A
Solution and Explanation
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.
