Options

A. 400
B. 300
C. 500
D. 200

Answer

To solve the problem, we need to determine the maximum marks in the examination based on the information given.

### Step-by-Step Solution:

1. **Understand the Passing Criteria:**
The student needs to secure 35% of the maximum marks to pass.

2. **Identify the Marks Obtained and the Failure Margin:**
The student scored 70 marks but failed by 70 marks. This means that the passing marks are 70 marks more than what the student scored.

\[ \text{Passing Marks} = \text{Marks Obtained} + \text{Marks Failed By} \]
\[ \text{Passing Marks} = 70 + 70 = 140 \]

3. **Set Up the Equation for Maximum Marks:**
Since the passing marks are 35% of the maximum marks, we can express this as:

\[ 0.35 \times \text{Maximum Marks} = 140 \]

4. **Solve for Maximum Marks:**
To find the maximum marks, we rearrange the equation:

\[ \text{Maximum Marks} = \frac{140}{0.35} \]

5. **Calculate the Maximum Marks:**
Performing the division:

\[ \text{Maximum Marks} = 140 \div 0.35 = 400 \]

### Conclusion:
The maximum marks in the examination are **400**.
