Consider the following pairs:
| Reservoirs | States | |
|---|---|---|
| 1. | Ghataprabha | Telangana |
| 2. | Gandhi Sagar | Madhya Pradesh |
| 3. | Indira Sagar | Andhra Pradesh |
| 4. | Maithon | Chhattisgarh |
How many pairs given above are not correctly matched?
Answer & explanation
Answer: (c) Only three pairs
Only Gandhi Sagar (Madhya Pradesh) is correctly matched, so three pairs are wrong. Ghataprabha (Hidkal) is in Karnataka, Indira Sagar is in Madhya Pradesh and Maithon is in Jharkhand.
- ✗ 1. The Ghataprabha (Hidkal) reservoir is in Karnataka, not Telangana.
- ✓ 2. Gandhi Sagar is on the Chambal river in Madhya Pradesh.
- ✗ 3. Indira Sagar is a multipurpose project on the Narmada in Madhya Pradesh, not Andhra Pradesh.
- ✗ 4. Maithon dam is on the Barakar river near Dhanbad in Jharkhand, not Chhattisgarh.
Remember · Gandhi Sagar (Chambal) and Indira Sagar (Narmada) are in Madhya Pradesh; Maithon (Barakar, DVC) is in Jharkhand; Ghataprabha's Hidkal reservoir is in Karnataka.
