1) Sufficient. since each paid more than country X, 56/5= 11.2 < 12 ,8 which is higher than X. so X is not the 6th member highest-contributing countries.

2) not Sufficient.

Answer is A

I take my above answer back....

1- Is not Sufficient, since it doesnt metioned the % of each country contribution.

So i pick E...

What is the OA?

I get C. Together, A and B seem sufficient to prove X was not in the top 6.

A cannot be true without the assumpution that contribution of X was (67.5-56) = 11.5 %, but there is nothing here to indicate that.

B: By itself again does not say enough since the other countries' contributions may have totalled (67.5-4.8)% while the other 153 countries are all less than 4.8%

(1) 56 percent of the total expenditures was paid by the 5 highest contributing countries, each of which paid more than country X

(2) Country X paid 4.8 percent of the total expenditures

(1) implies that the sixth-highest contributor paid 67.8-56=11.8% of the total expenditures. This would mean the each of the five highest contributors paid at least 11.8% of the total expenditures, so the sum of their shares would be at least 59%. This contradicts (1). Are you sure the question is well-written?

st 1 just says that each of 4 countries contributed more than x and contruibuted a net 56% using this we can not say anything abt X contribution.
It may or may not be amongst top contributors. SO insuff

st2 says x contributed 4.8% of total expenditure. insuff

Combining them also we can not for certain say that X is amongst top 6.
So my pick is E
