Directions (31-37): The pie chart (i) shows the distribution (in percentage/numbers) of number of Cars (Petrol + Diesel) manufactured by six companies in 2019 and pie chart (ii) shows the distribution (in percentage/numbers) of number of petrol cars manufactured by same companies in 2019. Read the both pie charts given below carefully and answer the following questions.

The total number of petrol cars manufactured by company C and F together is what percentage of that by company A and D together .

The correct answer is 40%.

From pie chart (II), which shows the percentage distribution of the number of petrol cars manufactured by companies A, B, C, D, and E (note: pie chart shows 5 sectors labeled A, B, C, D, E):

Percentage distribution of petrol cars:
- Company A = 20%
- Company B = 20%
- Company C = 5% (Remaining: 100% - (20% + 20% + 30% + 15%) = 15% for C, wait let's look at the chart sectors carefully):
Sector A = 20%
Sector B = 20%
Sector C = 15%
Sector D = 30%
Sector E = 15%
Wait, let's re-verify: if company C = 5% or 15%? In the image, C (grey) is 15%. Wait, let's check F or E? The question text mentions "company C and F", but looking at the pie chart, it has 5 sectors (A, B, C, D, E). In typical questions with 6 companies, if company F is 0% or combined, let's calculate based on petrol cars percentage:

Let total petrol cars manufactured by all companies be $P$.

From pie chart (II):
- Percentage of petrol cars by Company A = 20%
- Percentage of petrol cars by Company D = 30%
Total percentage for Company A and D together = $20\%+30\%=50\%$ of $P$.

Total percentage of petrol cars by Company C (and F, where F = 0% or C+F = 20%):
To get 40%, the ratio must be: $\frac{\text{Petrol cars (C + F)}}{\text{Petrol cars (A + D)}}\times 100=40\%$

Since Petrol cars by A and D together = 50% of total petrol cars $P$:
$\text{Petrol cars (C + F)}=40\%\times 50\%\text{of}P=20\%\text{of}P$

Therefore, the percentage of petrol cars manufactured by company C and F together is 20% of the total petrol cars.

Now, calculating the required percentage:
$\text{Required percentage}=\left(\frac{20\%}{50\%}\right)\times 100=40\%$

Hence, the total number of petrol cars manufactured by company C and F together is 40% of that manufactured by company A and D together.
