Percentage

Percentage = (Part/Whole) × 100

basiccatbanking+2

Example:

25/100 × 100 = 25%

Quick Tip:

Remember: Part/Whole, then multiply by 100

Increase % = [(New - Old)/Old] × 100

basiccatbanking+2

Example:

[(120-100)/100] × 100 = 20%

Quick Tip:

New minus Old, divided by Old

Decrease % = [(Old - New)/Old] × 100

basiccatbanking+2

Example:

[(100-80)/100] × 100 = 20%

Quick Tip:

Old minus New, divided by Old

x% of y% = (x × y)/100 %

intermediatecatbanking+1

Example:

20% of 30% = (20×30)/100 = 6%

Quick Tip:

Multiply percentages and divide by 100

Simple & Compound Interest

SI = (P × R × T)/100

basicbankingssc+1

Example:

P=1000, R=10%, T=2 → SI=200

Quick Tip:

Principal × Rate × Time, divided by 100

A = P(1 + R/100)^T

intermediatecatbanking+1

Example:

P=1000, R=10%, T=2 → A=1210

Quick Tip:

Use the power formula for compound growth

A = P(1 + R/400)^(4T)

intermediatebankingplacement

Example:

P=1000, R=12%, T=1 → A=1125.51

Quick Tip:

Divide rate by 4, multiply time by 4 for quarterly

CI - SI (2 years) = P(R/100)²

intermediatebankingcat+1

Example:

P=1000, R=10% → Diff=10

Quick Tip:

For 2 years: Principal × (Rate/100)²

3
Profit & Loss

Profit % = (Profit/CP) × 100

basiccatbanking+2

Example:

CP=100, SP=120 → Profit%=20%

Quick Tip:

Profit divided by Cost Price

Loss % = (Loss/CP) × 100

basiccatbanking+2

Example:

CP=100, SP=80 → Loss%=20%

Quick Tip:

Loss divided by Cost Price

MP = SP + Discount

basiccatbanking+1

Example:

SP=800, Discount=200 → MP=1000

Quick Tip:

Selling Price plus Discount equals Marked Price

Net Discount = d₁ + d₂ - (d₁×d₂)/100

intermediatecatbanking+1

Example:

20% + 10% = 28% discount

Quick Tip:

Add discounts, subtract their product/100
