• A. Number of labour experts from the Americas.
• B. Number of health experts from Europe.
• C. Number of health experts from Australasia.
• D. Number of experts in refugee relocation from Africa.

Answer 1

The correct option is D

Number of experts in refugee relocation from Africa.

(i) As the labour expert is half of each of the other, so the only possible combination is

(ii) Statement (d): If the number of Australasia expert is 1 less, i.e. total experts are 20

American experts will be twice as each of other.

The only combined possible is Americas 8.

Australasia 4 + 1 = 5

Europe 4

Africa 4

Now, we need to workout the various options possible in the blank cells.
