The Correct Option is A
Solution and Explanation
Step 1: List where the market share fell (1993 to 1994):
HD: Mumbai 20 to 15, Kolkata 35 to 30, Delhi 20 to 15. (Chennai rose.)
CO: Kolkata 30 to 15, Delhi 15 to 10, Chennai 20 to 15. (Mumbai rose.)
BN: Mumbai 45 to 40. (Kolkata rose; Delhi and Chennai unchanged.)
MT: Chennai 50 to 45. (Mumbai and Kolkata rose; Delhi unchanged.)
Step 2: Percentage decrease for each:
HD Mumbai: \(\dfrac{5}{20} = 25\%\); HD Kolkata: \(\dfrac{5}{35} \approx 14.3\%\); HD Delhi: \(25\%\).
CO Kolkata: \(\dfrac{15}{30} = 50\%\); CO Delhi: \(\dfrac{5}{15} \approx 33.3\%\); CO Chennai: \(\dfrac{5}{20} = 25\%\).
BN Mumbai: \(\dfrac{5}{45} \approx 11.1\%\).
MT Chennai: \(\dfrac{5}{50} = 10\%\).
Step 3: Maximum:
The largest decrease is 50% (CO in Kolkata). The values 60% and 53.3% do not occur anywhere in the table.
Final Answer:
The correct option is (1): 50%.
HD: Mumbai 20 to 15, Kolkata 35 to 30, Delhi 20 to 15. (Chennai rose.)
CO: Kolkata 30 to 15, Delhi 15 to 10, Chennai 20 to 15. (Mumbai rose.)
BN: Mumbai 45 to 40. (Kolkata rose; Delhi and Chennai unchanged.)
MT: Chennai 50 to 45. (Mumbai and Kolkata rose; Delhi unchanged.)
Step 2: Percentage decrease for each:
HD Mumbai: \(\dfrac{5}{20} = 25\%\); HD Kolkata: \(\dfrac{5}{35} \approx 14.3\%\); HD Delhi: \(25\%\).
CO Kolkata: \(\dfrac{15}{30} = 50\%\); CO Delhi: \(\dfrac{5}{15} \approx 33.3\%\); CO Chennai: \(\dfrac{5}{20} = 25\%\).
BN Mumbai: \(\dfrac{5}{45} \approx 11.1\%\).
MT Chennai: \(\dfrac{5}{50} = 10\%\).
Step 3: Maximum:
The largest decrease is 50% (CO in Kolkata). The values 60% and 53.3% do not occur anywhere in the table.
Final Answer:
The correct option is (1): 50%.

The Correct Option is B
Solution and Explanation
We count the number of products with increase in share (new>old):
Mumbai: HD↓, CO↑, BN↓, MT↑ → 2 increases
Kolkata: HD↓, CO↓, BN↑, MT↑ → 2 increases
Delhi: HD↓, CO↓, BN=, MT= → 0 increases
Chennai: HD↑, CO↓, BN=, MT↓ → 1 increase Minimum is 0 (Delhi).
Kolkata: HD↓, CO↓, BN↑, MT↑ → 2 increases
Delhi: HD↓, CO↓, BN=, MT= → 0 increases
Chennai: HD↑, CO↓, BN=, MT↓ → 1 increase Minimum is 0 (Delhi).

The Correct Option is D
Solution and Explanation
We check each product across 4 cities:
- HD: Mumbai↓, so fails.
- CO: Kolkata↓, so fails.
- BN: Mumbai↓, so fails. Thus, all have at least one city with a decrease.

The Correct Option is C
Solution and Explanation
Step 1: Check each product in each city (1993 to 1994):
HD: 20 to 15, 35 to 30, 20 to 15, 20 to 30. The only increase is 20 to 30, which is 1.5 times, not double.
CO: 20 to 25, 30 to 15, 15 to 10, 20 to 15. The only increase is 20 to 25, which is 1.25 times.
BN: 45 to 40, 25 to 35, 35 to 35, 10 to 10. The only increase is 25 to 35, which is 1.4 times.
MT: 15 to 20, 10 to 20, 10 to 10, 50 to 45. The increase 10 to 20 in Kolkata is exactly double. (15 to 20 is only 1.33 times.)
Step 2: Count:
Only MT doubled its share (in Kolkata). So 1 product.
Final Answer:
The correct option is (3): 1.
HD: 20 to 15, 35 to 30, 20 to 15, 20 to 30. The only increase is 20 to 30, which is 1.5 times, not double.

BN: 45 to 40, 25 to 35, 35 to 35, 10 to 10. The only increase is 25 to 35, which is 1.4 times.
MT: 15 to 20, 10 to 20, 10 to 10, 50 to 45. The increase 10 to 20 in Kolkata is exactly double. (15 to 20 is only 1.33 times.)
Step 2: Count:
Only MT doubled its share (in Kolkata). So 1 product.
Final Answer:
The correct option is (3): 1.
