Question

What is the ratio between marks obtained by Vedika in the subject Chemistry and Hindi to marks obtained by Bhavin in the subject English and Mathematics ?

• A. 0.8
• B. 1.5
• C. 1.0
• D. 1.6

Hint:

Since the values 153 and 152 are nearly identical, their ratio will be very close to 1. Comparing with the other options (0.8, 1.5, 1.6), Option (C) is the only reasonable choice.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
To find the required ratio, we calculate the sum of the specified marks for both students separately and then express the results as a ratio in its simplest fraction or decimal form.
Key Formula or Approach:
\[ \text{Ratio} = \frac{\text{Chemistry Marks of Vedika} + \text{Hindi Marks of Vedika}}{\text{English Marks of Bhavin} + \text{Mathematics Marks of Bhavin}} \]

Step 2: Detailed Explanation:
Let us extract the specific marks from the data table:
1. For Vedika:
- Chemistry marks = 74
- Hindi marks = 79
- Sum of Vedika's marks = \( 74 + 79 = 153 \)
2. For Bhavin:
- English marks = 74
- Mathematics marks = 78
- Sum of Bhavin's marks = \( 74 + 78 = 152 \)
3. Calculate the ratio:
\[ \text{Ratio} = \frac{153}{152} \] Since 153 is slightly greater than 152, let us convert the fraction to decimal form:
\[ \frac{153}{152} = 1.0065 \] Rounding this decimal to one decimal place gives 1.0.
The ratio between the two sets of marks is approximately 1.0.

Step 3: Final Answer:
The correct option is (C).
