Could someone be good enough to check the CG calculation as per the sketch below.

Tapered wing with straight trailing edge.
Root chord 450mm
Tip chord 250mm
Mean chord = 350mm
25% Cg = 25% of 350 =87.5 mm plus distance from mean chord to leading edge = 100 =187.5mm behind leading edge?

Thanks you mathematicians!
