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. Top 6 countries pay 67.8%. Was X among top 6? 1. Top 4 paid out 56%, X not among top 4. 2. X paid 4.8% of total. If top 4 paid 56%, that leaves 67.8-56=11.8% of total expenditures left. X paid 4.8% of total. Now it could be in the top six. Country 5: 7% Country 6: 4.8% OR, it might not be in the top five at all. Country 5: 6% Country 6: 5.8% Answer E

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) 56 percent of the total expenditures was paid by the 4 highest-contributing countries, each of which paid more than Country X --> just tells us that country X is 5th contributor or lower. Not sufficient. (2) Country X paid 4.8 percent of the total expenditures --> if all 6 highest contributors paid equal amount then each paid \frac{67.8}{6}=11.3%>4.8%, and the answer would be NO but if first contributor paid 51%, country X - 4.8% and the other 4 paid \frac{67.8-51-4.8}{4}=3%, then the answer would be YES. Not sufficient. (1)+(2) From (1) 5th and 6th contributed 67.8-56=11.8% (average of 4 highest contributing countries is \frac{56}{4}=14%). Now, if 5th and 6th contributed equal amount then 5_{th}=6_{th}=\frac{11.8}{2}=5.9>4.8%, and the answer would be NO but if 5th contributed 11.8-4.8=7% and 6_{th}=X=4.8% then the answer would be YES. Not sufficient. Answer: E.

67.8% by 6 countries (1) is not sufficient, as x could be in the remaning 12.8% or in (100 - 67.8)% part of contribution (2) is also not sufficient, because there is no break-up given for the other highest donors (1) + (2) Not sufficient as again country x's contrubtion relative to other countries is not known

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) 56% was paid by first 4 countries, X relative position among 153 + 2 is not available so it could be first , middle or last ... Insufficient 2) Does not provide relative position of X: Insufficient Combine 1 & 2 ; remaining of 67.8 -56 = 11.8 and 4.8 percent is X ; So it could be 7% 5th and 4.8% 6th or 6% 5th 5.8% 6th and 4.8 % 7th ... inconclusive -- E
