In a certain year the United Nations' total expenditures were $1.6 billion. Of this amount, 67.8 percent was paid by the 6 highest-contributing countries, and the balance was paid by the remaining 153 countries. Was country X among the 6 highest-contributing countries?
(1) 56 percent of the total expenditures was paid by the 4 highest-contributing countries, each of which paid more than Country X.
(2) Country X paid 4.8 percent of the total expenditures.
1.0848b paid by 6 highest contributing countries
0.5152 contributed by remaining 153 countries
Total = 159 countries
Insufficient. We do not know anymore information at this point.
country x paid = 0.0768b. but we do not know anything else.
Using St1 and St2:
We know 0.896b are paid off by the 4 highest-contributing countries. So we have 0.704b left to split up. Of this, 0.1888 is paid by the next two highest contributing countries. At this point, we still can't deduce if X is among the 6 highest contributing countries.
