Answer
50%

The correct answer is 50% — Thus the increase is 50%.

Step-by-step solution

  1. Identify the original value (Ajmer) = 1200 tonnes.
  2. Identify the new value (Bhopal) = 1800 tonnes.
  3. Compute the difference: 1800-1200 = 600 tonnes.
  4. Divide the difference by the original value: 600/1200 = 0.5.
  5. Convert to percentage: 0.5 × 100 = 50%.
  6. Thus the increase is 50%.
Common mistake: Using subtraction instead of division to find percentage.
