The simple interest formula allows us to calculate I, which is the interest earned or charged on a loan. According to this formula, the amount of interest is given by I = Prt, where P is the principal, r is the annual interest rate in decimal form, and t is the loan period expressed in years. The rate r must be converted from a percentage into decimal form.
Then, 2,000 = 1,000 * r * 10 ;
 Finally, r = 2 ÷ 10 = 20 ÷ 100 = 0.2
hope this helps you
