Answer 1

Answer:

The correct answer is -3.963%.

Explanation:

According to the scenario, the given data are as follows:

Interest rate = 7.85%

Rate of inflation = 12.3%

So, we can calculate the real interest rate by using the following method:

Real interest rate =[ (1 + Interest rate) ÷ ( 1 + inflation rate) ] - 1

By putting the value, we get,

Real interest rate =[ (1 + 0.0785) ÷ ( 1 + 0.123) ] - 1

= -3.963%

So, the purchasing power of your savings decreased by 3.963%.
