During the greatest ten-year change in nonminority scholarship funds awarded, which of the following most closely approximates the greatest five-year percent change in minority scholarship funds awarded?
(A) 15
(B) 25
(C) 27
(D) 33
(E) 43
It would be visually impossible to tell the difference, looking at a graph like this, between a 25% increase and a 27% increase. So those could never both be answer choices to a question like this, a question asking you to approximate from a graph with no way to determine exact values. Logically, they both are necessarily wrong just because if one was correct, the other would be a perfectly good approximation also, and the question can't have two right answers.
I also don't really understand the meaning of the first sentence, but I gather we're being asked to consider the period from 1980 to 1990, since non-minority scholarships changed then by a bigger amount than in the only other ten-year period displayed, from 1985 to 1995. Then we find the biggest percent increase in minority scholarships from 1980 to 1985, and if we estimate that they increased from $450 to $600, they increased by 150/450 = 33 1/3%. So I'd pick D here, but if you instead estimate the change to be from $470 to $600 (which doesn't seem unreasonable to me), you'd get an answer almost exactly equal to C, so the question seems as much a test of one's eyesight as of one's mathematical abilities.
