The surface's albedo of the incident light as a percent is determined as 30%.
The surface albedo quantifies the fraction of the sunlight reflected by the surface of the Earth.
The surface's albedo of the body is calculated as follows;
surface albedo = intensity of light reemitted / total intensity of light on the surface
surface albedo = 3/10 = 0.3
surface albedo = 0.3 x 100% = 30%
Thus, the surface's albedo of the incident light as a percent is determined as 30%.
