A disc rotates horizontal at the rate of 100 rpm and M.I. of the disc about the axis of rotation is `1kg m^(2)` . If a blob of molten wax weighing 50 gm drops gently at a distance 20 cm from the axis of rotation of the disc and remains stuck to it, then the increase in moment of inertia of the system will be
