What is the number of Model-Q cars sold in all cities together?
31555
To determine the number of Model-Q cars sold in all the cities together, we follow these steps:
- First, note that the total number of Maruti cars sold across these six cities is 90,000.
- We have the percentage distribution of cars sold in each city. Let's calculate the actual number of cars sold per city.
| City | % Distribution | Cars Sold | Proportion of Model-Q | Model-Q Cars Sold |
|---|---|---|---|---|
| A | 14.30% | \(90,000 \times \frac{14.30}{100} = 12,870\) | 7/(7+7+4) = \(\frac{7}{18}\) | \(12,870 \times \frac{7}{18} = 5,005\) |
| B | 16.20% | \(90,000 \times \frac{16.20}{100} = 14,580\) | 5/(2+5+2) = \(\frac{5}{9}\) | \(14,580 \times \frac{5}{9} = 8,100\) |
| C | 18.40% | \(90,000 \times \frac{18.40}{100} = 16,560\) | 3/(3+3+4) = \(\frac{3}{10}\) | \(16,560 \times \frac{3}{10} = 4,968\) |
| D | 16.80% | \(90,000 \times \frac{16.80}{100} = 15,120\) | 3/(4+3+2) = \(\frac{3}{9}\) | \(15,120 \times \frac{3}{9} = 5,040\) |
| E | 12.60% | \(90,000 \times \frac{12.60}{100} = 11,340\) | 2/(2+2+1) = \(\frac{2}{5}\) | \(11,340 \times \frac{2}{5} = 4,536\) |
| F | 21.70% | \(90,000 \times \frac{21.70}{100} = 19,530\) | 2/(3+2+5) = \(\frac{2}{10}\) | \(19,530 \times \frac{2}{10} = 3,906\) |
- Sum the number of Model-Q cars sold across all cities to find the total:
- \(5,005 + 8,100 + 4,968 + 5,040 + 4,536 + 3,906 = 31,555.\)
- Therefore, the total number of Model-Q cars sold in all cities together is 31,555.
Hence, the correct answer is:
- 31555
