Answer:

17.5years

The rule of 70 is used to determine how long it would take for a number to double depending on its growth rate. This is calculated with the formula;

70/Annual rate of return(in percentage)

Since we have determined the annual growth rate of the country to be 4 percent a year, we can approximately determine how many years it ill take to double its real GDP with the formula;

70/4

= 17.5years
