Homework? This is a poor example on how LMC might be used in the real world of engineering design...
#1 ignore the perpendicular MMC on the OD.
OD (datum B) LMC size= 50.4
Hole LMC size = dia. 4.6
Hole position tolerance allowed at LMC = dia. .4
Datum Bonus Tolerance allowed at LMC = dia. 0
Outer tangent edge of hole on radius.
For Hole size at LMC
40/2 (Basic or TED radius)
+ 4.6/2 (hole Outer Tangent Edge)
+ 0.4/2 (hole position tolerance start radius)
+ 0/2 (hole position bonus tolerance at radius)
+ 0/2 (Datum position bonus tolerance radius)
radius = 22.5
50.4/2 = 25.2 Radius of datum dia.
25.2-22.5 = 2.7 edge distance
Do the calculation on radius for each size don't forget bonus tolerance for hole and datum feature as they diverge.
Your book should show method.
