Core Math Breakdowns

  • Basic Fraction: (Percentage ÷ 100) × Number. Example: 20% of 500 becomes (20/100) × 500 = 100.
  • Percentage Increase: ((New Value - Old Value) ÷ Old Value) × 100. Example: A salary went from 500 to 600. Thus, the increase is exactly 20%.
  • Percentage Decrease: ((Old Value - New Value) ÷ Old Value) × 100. Example: A price dropped from 100 to 80. Consequently, the decrease is 20%.
  • X is what % of Y: (Part ÷ Total) × 100. Example: You scored 45 out of 50. Ultimately, this results in a 90% score.

Real-Life Practical Examples

Indeed, these specific calculations are utilized every single day. Therefore, here are some common scenarios where this utility shines:

  1. Shopping Discounts: You spot a shirt priced at ₹1000 featuring a "30% OFF" sticker. Use the primary tab to find that 30% of 1000 equals ₹300. Thus, you only pay ₹700.
  2. Stock Market Returns: You bought a stock at ₹200 and subsequently sold it at ₹250. Use the Increase tab to see you generated a 25% profit.
  3. Exam Results: If a student earns 450 marks out of a total of 600, use the final tab to quickly discover they scored exactly 75%.
Common Mathematical Mistake: Whenever calculating an Increase or Decrease, you must always divide by the original starting number, never the new one. Ultimately, this is where most individuals go wrong manually!
