The DAFNE -factory at Frascati is an e + e collider at the centre of mass

Question:

The DAFNE Φ-factory at Frascati is an e⁺e^– collider at the centre of mass energy equal to the ϕ mass. Calculate the ratio between the annihilation rates into K⁺K^– and K⁰K̅⁰ neglecting the mass difference between charged and neutral kaons. Is this a good approximation? Considering the case K⁰K̅⁰ calculate the relative frequency of K⁰₁K⁰₁, K⁰₁K⁰₂and K⁰₂K⁰₂.
