Total cars in all the four states = 8000

Now, for State 1: 

Total number of cars = 15% of the total cars = 15% of 8000 = 1200

Now, the number of diesel, petrol and electric cars are in the ratio of 3:4:1.

Total number of diesel cars = $$\dfrac{3}{3+4+1}\times1200=450$$

Total number of petrol cars = $$\dfrac{4}{3+4+1}\times1200=600$$

Total number of electric cars = $$\dfrac{1}{3+4+1}\times1200=150$$

Now, for State 2:

Total number of cars = 20% of the total cars = 20% of 8000 = 1600

Now, the number of diesel, petrol and electric cars are in the ratio of 5:3:2.

Total number of diesel cars = $$\dfrac{5}{5+3+2}\times1600=800$$

Total number of petrol cars = $$\dfrac{3}{5+3+2}\times1600=480$$

Total number of electric cars = $$\dfrac{2}{5+3+2}\times1600=320$$

Now, for State 3:

Total number of cars = 30% of the total cars = 30% of 8000 = 2400

Now, the number of diesel, petrol and electric cars are in the ratio of 4:5:3.

Total number of diesel cars = $$\dfrac{4}{4+5+3}\times2400=800$$

Total number of petrol cars = $$\dfrac{5}{4+5+3}\times2400=1000$$

Total number of electric cars = $$\dfrac{3}{4+5+3}\times2400=600$$

Now, for State 4:

Total number of cars = 35% of the total cars = 35% of 8000 = 2800

Now, the number of diesel, petrol and electric cars are in the ratio of 7:5:2.

Total number of diesel cars = $$\dfrac{7}{7+5+2}\times2800=1400$$

Total number of petrol cars = $$\dfrac{5}{7+5+2}\times2800=1000$$

Total number of electric cars = $$\dfrac{2}{7+5+2}\times2800=400$$

Hence, the distribution of the cars are as follows: 

Now, Number of diesel cars in state 4 = 1400

Number of electric cars in state 3 = 600

Ratio = $$\dfrac{1400}{600}=\dfrac{7}{3}$$

Hence, the ratio of the number of diesel cars in state 4 to the number of electric cars in state 3 is 7:3. 

$$\therefore\ $$ The required answer is 7:3.

Total cars in all the four states = 8000

Now, for State 1:

Total number of cars = 15% of the total cars = 15% of 8000 = 1200

Now, the number of diesel, petrol and electric cars are in the ratio of 3:4:1.

Total number of diesel cars = $$\dfrac{3}{3+4+1}\times1200=450$$

Total number of petrol cars = $$\dfrac{4}{3+4+1}\times1200=600$$

Total number of electric cars = $$\dfrac{1}{3+4+1}\times1200=150$$

Now, for State 2:

Total number of cars = 20% of the total cars = 20% of 8000 = 1600

Now, the number of diesel, petrol and electric cars are in the ratio of 5:3:2.

Total number of diesel cars = $$\dfrac{5}{5+3+2}\times1600=800$$

Total number of petrol cars = $$\dfrac{3}{5+3+2}\times1600=480$$

Total number of electric cars = $$\dfrac{2}{5+3+2}\times1600=320$$

Now, for State 3:

Total number of cars = 30% of the total cars = 30% of 8000 = 2400

Now, the number of diesel, petrol and electric cars are in the ratio of 4:5:3.

Total number of diesel cars = $$\dfrac{4}{4+5+3}\times2400=800$$

Total number of petrol cars = $$\dfrac{5}{4+5+3}\times2400=1000$$

Total number of electric cars = $$\dfrac{3}{4+5+3}\times2400=600$$

Now, for State 4:

Total number of cars = 35% of the total cars = 35% of 8000 = 2800

Now, the number of diesel, petrol and electric cars are in the ratio of 7:5:2.

Total number of diesel cars = $$\dfrac{7}{7+5+2}\times2800=1400$$

Total number of petrol cars = $$\dfrac{5}{7+5+2}\times2800=1000$$

Total number of electric cars = $$\dfrac{2}{7+5+2}\times2800=400$$

Hence, the distribution of the cars are as follows:

Now, Number of electric cars in state 4 = 400

Out of these 400 cars, 45% of them are AC and 55% of them are non AC cars. 

Number of non AC cars = 55% of 400 = 220 

Hence, state 4 has 220 non AC electric cars. 

$$\therefore\ $$ The required answer is B.

It is given that G and F are immediate neighbours. It means that no one is sitting between G and F.

So, we can remove the options C, D and E as in these cases, G and F are not immediate neighbours. 

Now, it is given that C is sitting fourth from one end. 

It means that C can either sit fourth from the left or fourth from the right. 

But in option B, it is given that C is sitting 3rd from the left. So, we can eliminate this option. 

Hence, we are left with option A as the answer. 

The correct arrangement is : (A, D, H, E, C, G, F, B) or (A, D, H, E, C, F, G, B) 

$$\therefore\ $$ The required answer is A.
