I need help with the following 2 questions, please.

The real risk-free rate is 3.85%. Inflation is expected to be 4.49% this year and 4.46% during the next 3 years. Assume that the maturity risk premium is zero (0). What is the yield on 3-year treasury securities?

A company's 6-year bonds are yielding 8.52% per year. Treasury bonds with the same maturity are yielding 4.81% per year, and the real risk-free rate (r*) is 2.05%. The average inflation premium and the maturity risk premium are the same for all maturities irrespective of the issuer. If the liquidity premium is 0.69%, what is the default risk premium on the corporate bonds?
