Question Details

The total number of petrol cars sold by E is 33.33% more than that of the total number of EV cars sold by C. If the total number of diesel cars sold by E is two-fifths of the total number of petrol cars sold by D and the total number of cars sold by E is two times that of A, then find the difference between the total number of EV cars sold by E and the total number of diesel cars sold by C.

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 .

Solution :

The correct answer is 488.

Let us solve the problem step-by-step.

First, we analyze the data given in the table for each company (A, B, C, and D) and the note.
Note: Petrol cars sold > Diesel cars sold for each company.
Let EV be the number of EV cars, P be the number of petrol cars, and Ds be the number of diesel cars sold.
For any company, the total number of cars sold is:
Total=EV+P+Ds

Let's calculate the details for Company C:
Total cars sold by C = 360
Percentage of EV cars sold by C = 30%
Therefore, the number of EV cars sold by C is:
EVC=360×30%=108
The remaining cars (Petrol + Diesel) sold by C is:
PC+DsC=360-108=252
The difference between petrol and diesel cars sold by C is 52. Since petrol cars sold are more than diesel cars:
PC-DsC=52
Adding the two equations:
2PC=252+52=304PC=152
Subtracting the equations:
2DsC=252-52=200DsC=100

Let's calculate the details for Company D:
Total cars sold by D = 280
Percentage of EV cars sold by D = 15%
Number of EV cars sold by D is:
EVD=280×15%=42
The remaining cars (Petrol + Diesel) sold by D is:
PD+DsD=280-42=238
The difference between petrol and diesel cars sold by D is 102:
PD-DsD=102
Adding these two equations:
2PD=238+102=340PD=170

Now, let us find the details for Company E using the given relationships:
1) The total number of petrol cars sold by E is 33.33% more than that of the total number of EV cars sold by C.
Note that 33.33% is equivalent to 13.
PE=EVC×(1+13)=108×43=36×4=144
2) The total number of diesel cars sold by E is two-fifths (25) of the total number of petrol cars sold by D.
DsE=25×PD=25×170=2×34=68
3) The total number of cars sold by E is two times that of A.
Total cars sold by A = 400
Therefore, Total cars sold by E is:
TotalE=2×400=800

Now we can determine the number of EV cars sold by E:
EVE=TotalE-(PE+DsE)
EVE=800-(144+68)=800-212=588

Finally, we calculate the difference between the total number of EV cars sold by E and the total number of diesel cars sold by C:
Difference=EVE-DsC
Difference=588-100=488
