A concrete column carries an axial load of 450 kN and a bending moment of 60 kNm at its base. An isolated footing of size 2m × 3m with the 3 m side along the plane of the bending moment is provided under the column. Centres of gravity of the column and the footing coincide. The net maximum and minimum pressures, in kPa, on the soil under the footing are, respectively
