The vertical normal force will just try to balance the weight of the man from above. Hence 2N=mg
$\implies N=400$

Contact force =N+N =2N
2N=80g.                           (g=9.8)
N=392
Torque equation for left side in earlier
So we take angle as 30°
N(2)tan30°=T(1)
2N*1/√3=T
T=2N/√3
T= 450N

If u take g = 10 then answer will be 470.58
