A measurement of the ratio of the branching fractions of the B-s(0) meson to J/psi f(0)(980) and to J/psi phi(1020) is presented. The J/psi, f(0)(980), and phi(1020) are observed through their decays to mu(+)mu(-), pi(+)pi(-), and K+K-, respectively. The f(0) and the phi are identified by requiring |M-pi+(pi)- - 974 MeV| LT 50 MeV and |M-K+(K)- - 1020 MeV| LT 10 MeV. The analysis is based on a data sample of pp collisions at a centre-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 5.3fb(-1). The measured ratio is B(B-s(0) - GT J/psi f(0)) B(f(0) - GT pi(+)pi(-))/B(B-s(0) - GT J/psi phi) B(phi - GT K+K-)= 0.140 +/- 0.008 (stat) +/- 0.023 (syst), where the first uncertainty is statistical and the second is systematic.
