Answer:
Correct option is (c)
Explanation:
Nominal interest rate is the sum of real interest rate and inflation. The lender charged nominal interest rate of 15% expecting inflation to be 10% in the following year. However, inflation was 12%. So, nominal rate becomes 17% (12% + 5%).
The lender should have charged a nominal interest rate of 17% instead of 15%. Now, he has to bear the loss of 2%. Borrower on the other hand benefited as he is paying lower interest rate than what is prevailing in the market.
