I call this a "sum and difference problem" because we are given the total of two values and the difference between them. As you can see here, the larger of the two values is the average of the given numbers, their sum divided by 2. This is the generic solution to such a problem: the larger number is the average of the given sum and difference.

Answer:
12.05%
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 12.050249999994%/100 = 0.12050249999994 per year,
then, solving our equation
I = 2000 × 0.12050249999994 × 0.666666666667 = 160.67
I = $ 160.67
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 12.050249999994% per year
for 0.666666666667 years is $ 160.67.
