Hi there,

Could you explain in the simplest this concept and how to resolve it

Person A invests x dollars, and person B invests y dollars. A earns an annual interest of 4%, B
earns an annual interest of 6%. The interest is compounded annually. What is the ratio of the
original investment of person A to that of person B ?

(1) At the end of the second year, the interests earned by A and B is equal.
(2) At the end of the second year, A earns an interests of $400, and B earns interest of $500.
