The total number of defective to non-defective EV cars sold by D is in the ratio of 3:4 respectively. The total number of defective petrol cars sold D is three times more than that of defective EV cars sold. Find the total number of non-defective EV and petrol cars sold by D.

Read the following table carefully and answer the questions given below. The table shows the total number of cars (EV, Diesel and petrol) sold and the percentage of EV cars sold out of the total cars sold by four different companies. The table also shows the difference between the petrol and diesel cars sold by these four companies.

Note: Petrol cars sold are more than the diesel cars sold by each company .

Companies	Total number of cars sold	Percentage of EV cars sold	Difference between the petrol and the diesel cars sold
A	400	25%	70
B	550	10%	85
C	360	30%	52
D	280	15%	102

The correct answer is 122.

First, we determine the number of different types of cars sold by Company D from the given table:

Total number of cars sold by D = 280

Percentage of EV cars sold by D = 15%

Therefore, the number of EV cars sold by D is:
$\mathrm{EV}=280\times \frac{15}{100}=42$

The remaining cars sold by D are Petrol and Diesel cars:
$\mathrm{Petrol}+\mathrm{Diesel}=280-42=238$

We are given that the difference between the Petrol and Diesel cars sold by D is 102, and Petrol cars sold are more than Diesel cars. Thus:
$\mathrm{Petrol}-\mathrm{Diesel}=102$

Adding the two equations, we get:
$2\times \mathrm{Petrol}=238+102=340$
$\mathrm{Petrol}=170$

Next, let's analyze the defective and non-defective EV cars for D:
The ratio of defective to non-defective EV cars is 3:4 respectively.
Total EV cars = 42.
Sum of ratio parts = 3 + 4 = 7 parts.
Number of defective EV cars is:
$42\times \frac{3}{7}=18$
Number of non-defective EV cars is:
$42\times \frac{4}{7}=24$

Now, let's find the number of defective and non-defective Petrol cars for D:
The total number of defective petrol cars sold by D is three times more than that of defective EV cars sold.
Number of defective Petrol cars is:
$18+(3\times 18)=18+54=72$
Number of non-defective Petrol cars is:
$170-72=98$

Finally, the total number of non-defective EV and petrol cars sold by D is:
$24+98=122$
