What is the age of a mineral that contains 25 percent parent and potassium 40 and argon 40 and 75 percent daughter and the half life potassium 40 is 1.25 billion years?

The age of the mineral can be estimated using the ratio of parent to daughter isotopes. With 25% parent (K40) and 75% daughter (Ar40), this would correspond to three half-lives since 25% is reduced by half three times to reach 75%. Given the half-life of K40 is 1.25 billion years, the age of the mineral would be approximately 3.75 billion years old.
