Yes, provided you know (or able to estimate) the concrete compressive strength & reinforcing steel yield strength. Calculate required maximum steel area per code (corresponding to Maximum Steel Ratio in tension), for the given beam size & compare it with the actual (provided) steel area. In case actual steel area in tension zone is more than the Code Permitted Maximum steel area, and the reinforcement area provided in compression zone is at least equal to the excess amount of reinforcement area provided in tension zone (= the difference of actually provided minus Code Maximum steel area in tension), the given beam will be a doubly reinforced beam.
