I’m not sure where you got the “90,27” from.
You are due south of the VOR so to fly to it you must fly 000 True.
You are on the 094°55.3W meridian so adding this convergence to your True course will give a course of 094°55.3 Grid.
But you need to compensate for 6 degrees left drift so adding 6 degrees gives grid heading of 094°55.3W + 6 = 100°55.3.
Rounding these up to the nearest degree give Heading 101 Grid and the VOR is 6 degrees to your left which is 095 Grid.
