Suppose you borrow $1,000 of principal that must be repaid at the end of two years, along with interest of 5 percent a year. If the annual inflation rate turns out to be 10 percent,

(a) What is the real rate of interest on the loan?

For this I got -5%.

(b) What is the real value of the principal repayment?
