The evidence of direct CP violation in the decays D+ → Ksπ+ and D+ → KsK+ was analyzed by a high-statistics sample of a photoproduced charm from the FOCUS experiment. The branching ratio for the decays were measured relative to each other and to D+ → K-π+π+. The relative branching ratio were improvement over earlier measurements and the measured CP asymmetries for the nodes were found to be consistent with zero.
