  2. 19
  3. 82·5
  4. 81

Correct answer and explanation

Correct answer: 82·5

Explanation: ✅ Correct Answer: C. 82·5 📚 Explanation: The amount to be excluded is 40 - 7 = 33 meters. To find the percentage, we divide the excluded part by the original length: (33 / 40) x 100. This simplifies to 330 / 4, which equals 82.5. Therefore, 82.5 percent of the cloth should be excluded to leave a remaining portion of 7 meters.
