Question

In a survey, 60 % of 200 students prefer online classes, and 25 % of the remaining prefer hybrid classes. How many students prefer neither?

• A. 20
• B. 60
• C. 40
• D. 50

Hint:

For percentage problems, calculate each group step-by-step, subtract from the total to find the remainder, and verify calculations against options.

Answer 1

The Correct Option is B

To solve the problem, we need to find how many students prefer neither online nor hybrid classes based on the given percentages.

1. Understanding the Concepts:

- Total students: 200
- Online class preference: 60% of 200
- Hybrid class preference: 25% of the remaining students who do not prefer online classes
- Neither: Students who prefer neither online nor hybrid classes

2. Calculate Number of Students Preferring Online Classes:

\[ 60\% \text{ of } 200 = \frac{60}{100} \times 200 = 120 \]

3. Calculate Remaining Students:

\[ 200 - 120 = 80 \]

4. Calculate Number Preferring Hybrid Classes:

\[ 25\% \text{ of } 80 = \frac{25}{100} \times 80 = 20 \]

5. Calculate Number Preferring Neither:

\[ 80 - 20 = 60 \]

Final Answer:

The number of students who prefer neither online nor hybrid classes is 60.
