What do you think is wrong with that paragraph? The conclusion (the sentence starting 'thus') does not follow from the premises. If we accept the premises as true then, depending on whether the 6700 is the overall average or the average not including grande ecole students, the % should be either 9% or 10%. No sensible calculation from those figures yields 30%. It’s just saying that limited funding is disproportionally directed to the Grande Ecoles, leaving the other schools with much less funding. By my calculation from the provided figures, equalizing the per capita funding for all students would increase the funding of other schools by just 4.7% to 5.2%.
