The ratio of branching fractions $$R_{K/π}$$ B(B$$^+_c$$ → J/$$Ψ$$K$^+$)/B(B$$^+_c$$ → J/$Ψπ^+)$ is measured with pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 TeV and 8 TeV, corresponding to an integrated luminosity of 3 fb-1. It is found to be $$R_{K/π}$$ = 0.079 ± 0.007 ± 0.003, where the first uncertainty is statistical and the second is systematic. This measurement is consistent with the previous LHCb result, while the uncertainties are significantly reduced.
