A circular plate with I = 0.052 kg m² is rotating at w; = 1.2 rad/s. Another circular plate with I2 = 0.038 kg m² is not rotating and dropped on the first plate. How fast is the combination rotating now of? Note that they are both rotating about their center of mass. The key here is that angular momentum L=I @ is conserved and your final moment of inertia is If= I1 + I2.
