Arti has to answer 30 multiple-choice questions in an assignment. She has answered 24 questions correctly. What percentage of questions has she got correct?

Answer

To find the percentage of questions Arti answered correctly, we can follow these steps:

### Step 1: Identify the total number of questions and the number of correct answers.
- Total number of questions = 30
- Number of questions answered correctly = 24

### Step 2: Use the formula for percentage.
The formula to calculate the percentage of correct answers is:
\[ \text{Percentage} = \left( \frac{\text{Number of correct answers}}{\text{Total number of questions}} \right) \times 100 \]

### Step 3: Substitute the values into the formula.
Substituting the known values into the formula gives:
\[ \text{Percentage} = \left( \frac{24}{30} \right) \times 100 \]

### Step 4: Simplify the fraction.
To simplify \(\frac{24}{30}\):
- Divide both the numerator and the denominator by 6:
\[ \frac{24 \div 6}{30 \div 6} = \frac{4}{5} \]

### Step 5: Convert the fraction to a percentage.
Now, calculate:
\[ \frac{4}{5} \times 100 = 80 \]

### Final Answer:
The percentage of questions Arti answered correctly is **80%**.
