Solution
Out of A, B, C, D & E, three are developed countries, and two are developing countries.
a) Country A is a developed country.
b) It is given that no two developing countries will sit next to each other and country D will always be seated next to a developing country.
Hence country D is a developed country.

Country A will always take a seat as far as possible from country B. Two arrangements are possible.
No two developing countries will sit next to each other. Hence, 'E' can take only one position.
