Mathematics
Percentage: x% of y = xy/100; a percentage increase from P to Q is ((Q − P)/P) × 100.
Simple interest SI = PRT/100; compound interest CI = P(1 + R/100)^T − P.
Profit percent = ((SP − CP)/CP) × 100; loss percent = ((CP − SP)/CP) × 100.
Average = sum of observations ÷ number of observations; total = average × number.
Rectangle area = l × b, perimeter = 2(l + b); circle area = πr², circumference = 2πr.
Triangle area = ½ × base × height; right triangle relation a² + b² = c².
For two numbers, LCM × HCF = product of the numbers; HCF divides both numbers exactly.
Speed = distance ÷ time; time = distance ÷ speed; distance = speed × time.
