We report on measurements of the branching ratios of the decays B{sup +}{yields}{chi}c10(1P)K{sup +} and B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -}, where {chi}{sub c1}{sup 0}(1P){yields}J/{psi}{gamma} and J/{psi}{yields}{mu}{sup +}{mu}{sup -} in p{bar p} collisions at sqrt[s]=1.8 TeV. Using a data sample from an integrated luminosity of 110 pb-1 collected by the Collider Detector at Fermilab we measure the branching ratios to be BR(B{sup +}{yields}{chi}{sub c1}{sup 0}(1P)K{sup +})=15.5{+-}5.4(stat){+-}1.5(syst){+-}1.3(br)x10{sup -4} and BR(B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -})=6.9{+-}1.8(stat){+-}1.1(syst){+-}0.4(br)x10{sup -4} where (br) is due to the finite precision on BR(B{sup +}{yields}J/{psi}K{sup +}), BR({chi}{sub c1}{sup 0}(1P){yields}J/{psi}{gamma}) is used to normalize the signal yield, and (syst) encompasses all other systematic uncertainties.
