Geotechnical engineering -2 (foundation engineering)

Solve the following problem with complete solution thank you so much here is 5:09pm i need it by 5:50pm thanks! :) 

Problem 1.A column 425mm x 425mm supports a dead load of 850kN and a live load of
750KN. The allowable soil bearing pressure is 260kPa. The base of the square footing is
1.25m below the grade. Assume weight of concrete is 23.5kN/m3 and that of soil is
17KN/m3. Total depth of footing is 675mm and has an effective depth of 575mm.
a. Which of the following gives the effective soil pressure?
b. Which of the following gives the dimension of the footing?
c. Which of the following gives the shear stress for a two-way shear stress?
