Given GDP is $20 trillion and increased GDP is $40 trillion.
Gross domestic product (GDP) is the standard measure of value added generated by the country's production of goods and services over a certain time period. GDP is the total monetary or market worth of all completed products and services produced within a country's boundaries in a certain time period.
As such, it also accounts for the money generated by such output, as well as the overall amount spent on final products and services (less imports).
Time take to reach $40 trillion is to be found.
Formula to find the time taken to reach $40 trillion is given below:
F = P *(1+i) ^t
Here,
F = 40,
P = 20,
I = 10%
Now put the values in the formula given above.
F = 0.1040 = 20 × (1+0.10) ^t(1.10)^t
= 40 / 20
= 2
Taking log both sides t = log 2 / log 1.10
= 7.27 yrs or 7 yrs
Therefore, it will take 7 years.

<h3>What is
average annual economic growth rate (AAGR) ?</h3>
The average annualised return of a portfolio, asset, or cash flow over time is known as the average annual growth rate, or AAGR.
The basic arithmetic mean of a set of returns is used to calculate AAGR.
Calculation for average annual economic growth rate:
Real per capita GDP in Singapore in 1957 was about $400 and it doubled to about $800.00 by 1979 over the period of 22 years.
Growth rate = 
The last value = $800
The initial value = $400
n = number of years
Growth rate = 
= 
= 1.032 - 1
= 0.032
Growth rate % = 0.032×100
= 3.2%
Therefore, the growth rate in Singapore over 22 years are 3.2%.
