A search is made for the highly-suppressed B   meson decays B+→K+K+π&minus;B+→K+K+π&minus; and B+→π+π+K&minus;B+→π+π+K&minus; using a data sample corresponding to an integrated luminosity of 3.0 fb&minus;1 fb&minus;1 collected by the LHCb experiment in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B(B+→K+K+π&minus;)<1.1&times;10&minus;8B(B+→K+K+π&minus;)<1.1&times;10&minus;8 and B(B+→π+π+K&minus;)<4.6&times;10&minus;8B(B+→π+π+K&minus;)<4.6&times;10&minus;8.
