The table given below shows the data about track record of car racing game, where 4 cars P, Q, R and S are competing to reach finishing line which is at a distance of 3000 m from their initial starting point.

1. Drift refers to over starting intentionally done by driver.
2. While calculating average speed, do not consider time taken in drift/crash.
3. Points = 50 × drifts – 20 × crashed

Cars	Drift	Time to reach finishing line (in sec)	Crash
P	5	180	3
Q	7	120	5
R	6	150	4
S	8	100	6

Which car earned maximum points at the end of the race?

The correct option is car S.

To find which car earned the maximum points at the end of the race, we use the formula given for calculating points:

$\text{Points}=50\times \text{drifts}-20\times \text{crashed}$

Note: We do not need to consider the distance or the time to reach the finishing line, as they are not part of the points formula.

Let us calculate the points for each car step-by-step:

1. For Car P:
Drifts = 5, Crashes = 3

$\text{Points for P}=50\times 5-20\times 3=250-60=190$

2. For Car Q:
Drifts = 7, Crashes = 5

$\text{Points for Q}=50\times 7-20\times 5=350-100=250$

3. For Car R:
Drifts = 6, Crashes = 4

$\text{Points for R}=50\times 6-20\times 4=300-80=220$

4. For Car S:
Drifts = 8, Crashes = 6

$\text{Points for S}=50\times 8-20\times 6=400-120=280$

Comparing the final points:
- Car P: 190 points
- Car Q: 250 points
- Car R: 220 points
- Car S: 280 points

Car S earned the maximum number of points (280 points) at the end of the race.
