By analyzing 2.93 fb-1 of e+e- collision data taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, the branching fractions of the inclusive decays D+ & RARR; K0SX and D0 & RARR; K0SX are measured to be (33.11 & PLUSMN; 0.13 & PLUSMN; 0.36)% and (20.75 & PLUSMN; 0.12 & PLUSMN; 0.20)%, respectively, where the first uncertainties are statistical and the second are systematic. These results are consistent with the world averages of previous measurements, but with much improved precision.
