The answer should be A
20 cent times 5 times 4 we have 400:4:1
Basically we should make equal the 20cent with 4$.

I think including the world "spends the equivalent of" is an unnecessarily confusing phrase. Anyways... to the problem. We need to compute one ratio that unites all three people in question--let's call them B (billionaire), M (millionaire) and Y (yuppie).
B:M equals $20:0.20 or 100:1
M:Y equals 4:1
Let Y in the ratio we're looking for (Y:M:B) be 1--this means M = 4 and B = 4*100 = 400.
The final ratio should be 1:4:400. Choice A
B:M equals $20:0.20 or 100:1
M:Y equals 4:1
Let Y in the ratio we're looking for (Y:M:B) be 1--this means M = 4 and B = 4*100 = 400.
The final ratio should be 1:4:400. Choice A
