We investigate the structure and the tidal deformability of strange stars with a mirror-dark-matter core for the standard MIT bag model. We find that to explain the observations of GW170817, PSR J0740 + 6620 and PSR J0030 + 0451 simultaneously, strange stars in GW170817 should have a mirror-dark-matter core although it is unnecessary for PSR J0740 + 6620 and PSR J0030 + 0451 to contain one. More generally, our study leads to the result that for the standard MIT bag model, the observations of compact stars mentioned above could serve as evidence for the existence of a dark-matter core inside strange stars.
