Data analysis—current period, base period
current period
Recognition - Read the question to see the time, the material is given to the present, and the question stem asks for the past
formula
Base period = current period – growth amount
Base period = growth amount/growth rate
Base period = current period/1 growth rate
question type
Base period calculation
There is a big gap between options - just divide 2 digits
Small gap in options
Divide 3 digits
3-digit series formula, modified by proportion, denominator converted to 100
Base period sum difference—3-position formula, equal ratio correction, denominator equalization
Base period comparison
Analyze first
The current period is large, the growth rate is small, and the base period is large
The current period is small, the growth rate is large, and the base period is small
Compare again
vertical elimination
Horizontal multiple
3-digit series formula, modified by proportion, denominator is the same
base period

When reading questions, look at the time. The materials are given now, and the question stems are given later.
Iconic feature: If the growth rate/growth rate of... remains unchanged
formula
Current period = base period growth amount
Current period = base period × (1 growth rate)
question type
Current catch-up
Growth remains unchanged
Pursuing amount - required number of years (n) = current gap ÷ growth amount (not an integer, round up) The year required = base period year n
Chasing variables—number of years required (n) = current gap ÷ growth gap (not an integer, round up) The year required = base period year n
Current calculation
Growth rate remains unchanged
Give the growth amount: directly use the formula - current period = base period × (1 growth rate)
No growth rate
