1. so, 56% of expenditure was paid by the top four countries. and each paid more than X. well, we could assume that 1) is the 5th or 6th or 2)we could assume that its out of the big 6 => more than one reasoning for this => not suff.
2. country x paid 4.8 percent. again, this alone tells us nothing => not suff.
Combining 1 AND 2. well, it basically is saying that 56% is paid by the top 4, we know that the top six pays 67.1%. which means 11.1% is shared between 5th or 6th. now, we could present that x is in the top 6 with 4.8 and the 5th paying 6.3% or we could assume that 11.1% is shared between 5th or 6th. Either way, there's more than one solution surfacing, hence ans = E?
Okey, this is my really simple basic math reasoning, would someone please stand up and explain this q in mathanese please?
