Please help me understand how to obtain the structures

The NMR spectra are shown for two isomeric compounds with formula C_10H_12O_2. Their infrared spectra show strong bands near 1735cm^-1. Make no attempt to interpret the aromatic proton area between 7.0 and 7.5 ppm except to determine the number of protons attached to the aromatic ring. Draw the structures of the compounds.
