not enough information to find "how many were taking each subject"
... can find how many passed each subject
... but no information on how many failed ... taking = passed + failed

75 passed both ... so (156 - 75) passed one or the other
... 9 more G than H ... G or H is 81 students

G = H + 9 ... 2 H + 9 = 81 ... solve for H , substitute back to find G

remember to add in the 75 who passed both
