Answer
20 students

The correct answer is 20 students — Conclude that 20 students belong to families earning less than ₹50,000 per year.

Step-by-step solution

  1. Identify the percentage that represents the target group: 10%.
  2. Convert the percentage to a decimal: 10% = 0.10.
  3. Multiply the total number of students by this decimal: 200 × 0.10 = 20.
  4. Round if necessary (the result is an integer).
  5. Conclude that 20 students belong to families earning less than ₹50,000 per year.
Common mistake: Using 10 of 200 instead of 10%
