What to Focus On

  • Percentage means 'per hundred' - always out of 100
  • To convert fraction to %: multiply by 100 and add % symbol
  • To convert % to fraction: divide by 100 and simplify

  • x% of Q = (x/100) × Q
  • Percentage = (Part/Whole) × 100
  • For increase: % increase = (Increase/Original) × 100

  • Profit = SP - CP, Loss = CP - SP
  • Profit% and Loss% are calculated on Cost Price only
  • SP = CP × (100 ± profit/loss%)/100

Common Mistakes to Avoid

In profit/loss problems, profit% and loss% are calculated on Selling Price (SP)

Discount% is calculated on Cost Price or Selling Price

Simple Interest and Compound Interest give the same result for any time period

Memory Tips

Basic percentage definition: r% = r/100

Converting fraction to percentage: multiply by 100

Converting percentage to decimal: divide by 100 (move decimal 2 places left)

Profit and Loss formula: Profit% = (SP-CP)/CP × 100
