Percentage
50% = 1/2
25% = 1/4
75% = 3/4
12.5% = 1/8
6.25% = 1/16
Simplification
BODMAS Rule
25 × n = (n ÷ 4) × 100
125 × n = (n ÷ 8) × 1000
99 × n = 100n − n
Multiplication Tricks
999 × n = 1000n − n
101 × n = 100n + n
Algebra
(a + b)² = a² + 2ab + b²
(a − b)² = a² − 2ab + b²
a² − b² = (a − b)(a + b)
Ratio & Proportion
a : b = a/(a+b)
a/b = c/d
Time & Work
(a × b) / (a + b)
Efficiency = 1/time
Speed & Distance
Speed = Distance / Time
1 km/hr = 5/18 m/s
Profit & Loss
Profit = SP − CP
Profit% = (Profit/CP) × 100
Average
Average = Sum / Number
Number Series
Check difference, ratio, squares, cubes
