In an examination it is required to get $296$ of the total maximum aggregate marks to pass. A student gets $259$ marks and is decided failed. The difference of marks obtained by the student and that required to pass is $5\%$. What are the maximum aggregate marks a student can get?

Answer
Correct Answer: 740
Explanation
### Concept & Logic
The problem directly states that the absolute difference between the passing marks and the obtained marks corresponds to exactly $5\%$ of the total maximum aggregate marks.
$$ \text{Passing Marks} - \text{Obtained Marks} = \text{Percentage Difference of Total} $$
### Step-by-Step Solution
* **Given:**
* Passing marks = $296$
* Obtained marks = $259$
* Percentage equivalent of the difference = $5\%$
* **Calculation:**
* First, find the absolute difference in marks:
$296 - 259 = 37$ marks.
* We are given that this difference is equal to $5\%$ of the total maximum marks.
* Let the maximum aggregate marks be $x$.
* $5\%$ of $x = 37$
* $\frac{5}{100} \times x = 37$
* $x = 37 \times 20 = 740$
### Exam Strategy & Shortcut
Recognize that $5\%$ is equivalent to the fraction $\frac{1}{20}$.
If $\frac{1}{20}$ of the total is $37$, simply multiply $37$ by $20$ to get the total $100\%$.
$37 \times 2 = 74$, so $37 \times 20 = 740$. This can be done mentally in seconds.
### Common Pitfall
Students sometimes overcomplicate by trying to find the passing percentage first. Since you are given the exact value of the $5\%$ margin, you can bypass intermediate steps and solve directly for the $100\%$ total.
### Final Answer
**Therefore, the correct answer is 740.**
