4.Current volume
1. Maintain growth
Question type: Maintain the increment, exceed for the first time...
Current volume = base period growth volume * N
①An A exceeds a certain amount
① Calculate the growth amount (try to be as accurate as possible to prevent critical values)
②It will be faster if you enter the option
②What year is A>B?
Move the two expressions together and move the term [Linear Inequality of One Variable]
③The difference range of AB in a certain year
If it is a small increase, that is, 143 and 198 are interchanged, it will be -55, and the direction can be subtracted.
2. Maintain growth rate
(1) Give the growth rate (estimate/actuarial)
Estimate
A* (1 8.6%)
①A*1.1
②A*{1 10% (-1.4%)}
③A*1 A*8.6% → front and back, inside and outside
Actuarial
A* (1 56.6%)
A*1 A*50% A*6.6%(1/15)
(2) Without giving the growth rate, find the current period
①r>0, the growth becomes larger
Direct ± price range
② Compounding profits: Overestimation and overestimation
Consecutive years: Estimated at the same ratio → principal and interest
Refer to other growth amounts
378***→451*** (1 times more) 9861→more than 10,000 (more than double)
(3) Calculate the current period based on the nominal growth rate
Nominal growth rate: the growth rate without deducting the impact of price factors Actual growth rate (calculated at comparable prices): Growth rate after deducting the impact of price factors
Formula 1
rnominal>rreal, consumer prices have risen
Formula 2: Current volume = Current volume/(1 r nominal) × (1 r actual)
Current volume = Current volume × {(1 r actual) ÷ (1 r nominal)}
Convert (1 6.9%) into 107 estimate Convert (1 9%) into 109 estimate The ratio is 1-
(4) Formula of the development process of things
Number of enterprises at the end of the previous year + number of new enterprises during the year - number of enterprises canceled during the year = number of enterprises at the end of the year
More details later
Equivalent to: base period net increment = current period; net increment = new addition - cancellation
(5) Relationship between base period and current period
Average book rate of return = (book exit return – total investment)/total investment; Premium rate = (residential sales price - floor price) / floor price;
Equivalent to: growth rate = (current period - base period) / base period → base period = current period / 1 r
