The Correct Option is A
Solution and Explanation
We compute the percentage decrease for each product in each city:
\[
\text{% Decrease} = \frac{\text{Old share} - \text{New share}}{\text{Old share}} \times 100
\]
Mumbai:
- HD: (20 - 15) / 20 × 100 = 25%
- CO: (20 - 25) → increase (ignore)
- BN: (45 - 40) / 45 × 100 ≈ 11.1%
- MT: (15 - 20) → increase (ignore) Kolkata: - HD: (35 - 30) / 35 × 100 ≈ 14.3%
- CO: (30 - 15) / 30 × 100 = 50%
- BN: (25 - 35) → increase (ignore)
- MT: (10 - 20) → increase (ignore) Delhi: - HD: (20 - 15) / 20 × 100 = 25%
- CO: (15 - 10) / 15 × 100 ≈ 33.3%
- BN: (35 - 35) = 0%
- MT: (10 - 10) = 0% Chennai: - HD: (20 - 30) → increase (ignore)
- CO: (20 - 15) / 20 × 100 = 25%
- BN: (10 - 10) = 0%
- MT: (50 - 45) / 50 × 100 = 10% Maximum decrease found = 50% for CO in Kolkat(a) But we must check for cases where the drop is bigger: none other exceed 50%. Therefore, answer is 50%. Wait — but option says 60%. Recheck: BN in Kolkata: (25 - 35) → actually increased, so ignore. Largest is indeed 50%, so final answer is (b) 50%.
- CO: (20 - 25) → increase (ignore)
- BN: (45 - 40) / 45 × 100 ≈ 11.1%
- MT: (15 - 20) → increase (ignore) Kolkata: - HD: (35 - 30) / 35 × 100 ≈ 14.3%
- CO: (30 - 15) / 30 × 100 = 50%
- BN: (25 - 35) → increase (ignore)
- MT: (10 - 20) → increase (ignore) Delhi: - HD: (20 - 15) / 20 × 100 = 25%

- MT: (50 - 45) / 50 × 100 = 10% Maximum decrease found = 50% for CO in Kolkat(a) But we must check for cases where the drop is bigger: none other exceed 50%. Therefore, answer is 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.
- CO: Kolkata↓, so fails.
- BN: Mumbai↓, so fails. Thus, all have at least one city with a decrease.

The Correct Option is A
Solution and Explanation
100% share means in that city the product has full market, which is not the case in any data row (all values<100). Therefore answer is 0.

The Correct Option is C
Solution and Explanation
Doubling condition: new share ≥ 2 × old share.
- HD: no city meets doubling.
- CO: no city meets doubling.
- BN: no city meets doubling.
- MT: Chennai: 50 → 45 (decrease), so fails doubling. Wait, recheck: doubling means new ≥ 2 × old, so check all cities for MT: Mumbai: 15→20 (not double), Kolkata: 10→20 (double), Delhi: 10→10 (no), Chennai: 50→45 (no). So MT meets condition.
- Another product? Check BN: Kolkata: 25→35 (<50) no. CO: 15→10 no. HD: 20→30 (not double). Thus only 1 product meets condition (MT), so answer is (b) 1.
- HD: no city meets doubling.
- CO: no city meets doubling.
- BN: no city meets doubling.
- MT: Chennai: 50 → 45 (decrease), so fails doubling. Wait, recheck: doubling means new ≥ 2 × old, so check all cities for MT: Mumbai: 15→20 (not double), Kolkata: 10→20 (double), Delhi: 10→10 (no), Chennai: 50→45 (no). So MT meets condition.
- Another product? Check BN: Kolkata: 25→35 (<50) no. CO: 15→10 no. HD: 20→30 (not double). Thus only 1 product meets condition (MT), so answer is (b) 1.
