Meenu purchased an item for ₹ 800 and sold the same for ₹ 1000. The gain percentage is

Detailed Solution: Question 9

To calculate the gain percentage, you can use the following formula:

Gain percentage = [(Selling Price - Cost Price) / Cost Price] × 100%

Let's break down the calculation step by step:

  • Given:
    • Selling Price = 1000
    • Cost Price = 800
  • Substituting the values into the formula:
  • Gain percentage = [(1000 - 800) / 800] × 100%
  • Calculating the difference:
    • 1000 - 800 = 200
  • Now, substitute this back into the equation:
  • Gain percentage = (200 / 800) × 100%
  • Now divide 200 by 800:
    • 200 / 800 = 0.25
  • Finally, multiply by 100%:
    • 0.25 × 100% = 25%

Therefore, the gain percentage is 25%.
