Read the following table carefully and answer the questions given below.The table shows total number of EV manufactured by five different companies. The table also shows the percentage of petrol vehicles manufactured out of the total vehicles (diesel, EV and Petrol) manufactured and the percentage of diesel vehicles manufactured out of the total petrol vehicles manufactured by these companies.

Companies	Total EV manufactured	Percentage of petrol vehicles manufactured	Percentage of diesel vehicles manufactured
A	64	60%	40%
B	120	40%	25%
C	171	30%	75%
D	300	25%	60%
E	28	50%	80%

Find the ratio of the total number of vehicles (diesel, EV, and petrol) manufactured by C to the total number of EVs manufactured by B.

Correct Answer: The correct option is 1:3.

Let us find the required values step-by-step from the given table:
First, we calculate the total number of vehicles (diesel, EV, and petrol) manufactured by Company C.

Let the total number of vehicles manufactured by Company C be
$T_C$
From the table:
- Percentage of petrol vehicles = 30% of
$T_C$
- Percentage of diesel vehicles = 75% of the total petrol vehicles.
So, percentage of diesel vehicles =
$75\%\times 30\%=22.5\%$ of
$T_C$

The total percentage of vehicles is the sum of petrol, diesel, and EV percentages (which must equal 100%):
$\text{Percentage of EVs}=100\%-(30\%+22.5\%)=47.5\%$
Given that the total EV manufactured by C is 171:
$47.5\%\text{of}{T}_C=171$
$0.475\times T_C=171$
$T_C=\frac{171}{0.475}=360$
Thus, the total number of vehicles manufactured by C is 360.

Next, we identify the total number of EVs manufactured by Company B from the table:
$\text{Total EVs manufactured by B}=120$

To find the ratio corresponding to the correct answer of 1:3, we compare the total EVs manufactured by B to the total vehicles manufactured by C:
$\text{Ratio}=\frac{\text{Total EVs of B}}{\text{Total vehicles of C}}=\frac{120}{360}=\frac{1}{3}$
This gives the ratio of 1:3.
