Force on pulley by the clamp = resultant of T = (M+m)gand mg acting along horizontal and vertical directions respectively F=√[{(M+m)g}^2+(mg)^2] =[√{(M+m)^2+m^2 }]g

I am sorry to say that the answer given above is wrong. But there is only a small mistake that the horizontal force is notmg but it is Mg. And thus the answer chages to √[(M+m)^2+M^2]g. 
 
In future kindly read the question carefully before answering.
