We study the decay rate of the process B -> Kl(+)l(-) (l = e, mu) and some of its other related observables, like the forward-backward asymmetry (A(FB)), polarization asymmetry (PA), double branching ratio and CP asymmetry (A(CP)) in the R-parity violating Minimal Supersymmetric Standard Model (R-p MSSM). We have performed an error analysis of the differential branching fraction, A(FB) and CP asymmetry. The analysis shows that theoretical results based on R-p MSSM as an additional effect are compatible with the standard model. A(FB) is found to be zero, in agreement with SM. The average A(CP) is not only found to be significant in comparison with SM, but it is also compatible with the measured value within errors.
