Options

A. 0.6
B. 0.63
C. 0.62
D. 0.65

Explanation

To find Amit's average percentage of marks, we can follow these steps:

### Step 1: Calculate the total marks scored by Amit.
Amit scored the following marks in five subjects:
- 50
- 60
- 45
- 80
- 75

**Total Marks = 50 + 60 + 45 + 80 + 75**

### Step 2: Add the marks together.
Calculating the total:
- 50 + 60 = 110
- 110 + 45 = 155
- 155 + 80 = 235
- 235 + 75 = 310

So, **Total Marks = 310**.

### Step 3: Calculate the total maximum marks.
The maximum marks for each subject is 100, and there are 5 subjects.

**Total Maximum Marks = 100 * 5 = 500**.

### Step 4: Calculate the average percentage of marks.
The average percentage is calculated using the formula:

\[ \text{Average Percentage} = \left( \frac{\text{Total Marks}}{\text{Total Maximum Marks}} \right) \times 100 \]

Substituting the values we found:
\[ \text{Average Percentage} = \left( \frac{310}{500} \right) \times 100 \]

### Step 5: Simplify the fraction.
Calculating the fraction:
\[ \frac{310}{500} = 0.62 \]

### Step 6: Convert to percentage.
Now, multiply by 100:
\[ 0.62 \times 100 = 62\% \]

### Final Answer:
Amit's average percentage of marks is **62%**.
