Calculate the rate of return for each bond between the first year (t) and the second year (t +1) when interest rate increases to 20%?

Please do in details rather than just answers.

Assuming that you are buying two different coupon bonds: Alpha and Beta with following conditions: Alpha: face value (par value) = $1000 coupon rate= 10% years to maturity= 5 - yield's to maturity (interest rate) = 10% the current price of Alpha bond, Pe=? Beta: face value (par value)= $1000 - coupon rate=10% years to maturity= 3 yield's to maturity (iterest rate)= 10% the current price of Beta bond, Pg=?
