Present Population when Natural Increase is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
present_population = Natural increase/((Average birth rate per year*Design period)-(Average death rate per year*Design period))
P = N/((IB*T)-(ID*T))
This formula uses 4 Variables
Variables Used
Natural increase- Natural increase is the difference between the numbers of births and deaths in a population.
Average birth rate per year - Average birth rate per year the arithmetic average of total birth within a year. (Measured in 1 Per Day)
Design period - Design period is the time span for which any particular water related structure is constructed. (Measured in Year)
Average death rate per year - Average death rate per year is the arithmetic mean of numbers of death within a year. (Measured in 1 Per Day)
STEP 1: Convert Input(s) to Base Unit
Natural increase: 10 --> No Conversion Required
Average birth rate per year: 3 1 Per Day --> 3.47222222222222E-05 1 Per Second (Check conversion here)
Design period: 20 Year --> 631139040 Second (Check conversion here)
Average death rate per year: 10 1 Per Day --> 0.000115740740740741 1 Per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P = N/((IB*T)-(ID*T)) --> 10/((3.47222222222222E-05*631139040)-(0.000115740740740741*631139040))
Evaluating ... ...
P = -0.000195564786213464
STEP 3: Convert Result to Output's Unit
-0.000195564786213464 --> No Conversion Required
FINAL ANSWER
-0.000195564786213464 <-- Present population
(Calculation completed in 00.031 seconds)
