Complete the table by filling in the missing values.

| | Gasoline | Diesel |
|--------------|----------|--------|
| Hakhlowk | 18 | 8 |
| Sian | 18 | 12 |
| SuN | 3 | 7 |

Then answer the following questions:

1. What percentage of all vehicles is Hakhlowk?
2. What percentage of SuN vehicles run on gasoline?
3. What percentage of gasoline vehicles are Sian?
4. What percentage of diesel vehicles are Sian?
```



Answer :

Certainly! Let's go through each of the questions step-by-step.

1. Percentage of "SuN" vehicles that ran on gasoline:

Firstly, we need to find the total number of "SuN" vehicles which is the sum of "SuN" vehicles that ran on gasoline and on diesel.

- "SuN" vehicles on gasoline: 3
- "SuN" vehicles on diesel: 7

Total "SuN" vehicles: [tex]\(3 + 7 = 10\)[/tex]

To find the percentage of "SuN" vehicles that ran on gasoline:

Percentage of "SuN" on gasoline: [tex]\(\frac{3}{10} \times 100 = 30.0\%\)[/tex]

2. Percentage of gasoline vehicles that are Sian:

Firstly, we need to find the total number of gasoline vehicles from all groups.

- Hakhlowk gasoline vehicles: 18
- Sian gasoline vehicles: 18
- SuN gasoline vehicles: 3

Total gasoline vehicles: [tex]\(18 + 18 + 3 = 39\)[/tex]

Now, we calculate what percentage of these gasoline vehicles are Sian:

Percentage of gasoline vehicles that are Sian: [tex]\(\frac{18}{39} \times 100 = 46.15\%\)[/tex]

3. Percentage of total vehicles that are diesels:

Firstly, we determine the total number of diesel vehicles from all groups.

- Hakhlowk diesel vehicles: 8
- Sian diesel vehicles: 12
- SuN diesel vehicles: 7

Total diesel vehicles: [tex]\(8 + 12 + 7 = 27\)[/tex]

Next, we find the total number of all vehicles:

- Total Hakhlowk vehicles: [tex]\(18 + 8 = 26\)[/tex]
- Total Sian vehicles: [tex]\(18 + 12 = 30\)[/tex]
- Total SuN vehicles: [tex]\(3 + 7 = 10\)[/tex]

Total vehicles: [tex]\(26 + 30 + 10 = 66\)[/tex]

Finally, we calculate the percentage of total vehicles that are diesels:

Percentage of diesel vehicles: [tex]\(\frac{27}{66} \times 100 = 40.91\%\)[/tex]

Thus, the detailed answers are:

- The percentage of "SuN" vehicles that ran on gasoline is 30.0%.
- The percentage of gasoline vehicles that are Sian is 46.15%.
- The percentage of total vehicles that are diesels is 40.91%.
