It will take 7 years.
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.
