Answers 1: (c)

Common solution for the set: It is given that Alan is one of the American experts in refugee relocation. From the table, there can be 1 more or 2 more American experts in the same category.

It is given that the number of labour experts is half the number of experts in each of the other categories. Let the number of labour experts be x.

Number of labour experts = 3 and number of experts in each of the other categories = 6.

Given that if there had been one less Arabian experts, then the Latin Americans would have had twice as many experts as each of the other continents. Let the number of Americans be 2y.

2y + y + (y + l) + y = 21 ∴ y = 4.

So the number of Americans = 8

Number of Arabs = 4 + 1 = 5

Number of Asians = 4

Number of North Americans = 4 It is also given that except Asia in labour category, every continent sent at least one expert in each category.

The correct option is (c).

Answers 2: (c) For the common solution for this set, refer to solution of Question 1. If Latin America had 1 expert in population studies, the remaining Americans should be distributed in 2 remaining fields i.e., 3+3. Hence the number of health experts from Latin America cannot be 2. The correct option is (c).

Answers 3: (d) For the common solution for this set, refer to solution of Question 1.

From the given choices, the statements in the first three choices are possible from the given table.

The statement in choice (d) i.e., Asia and the Latin America had 1 expert each in population studies attending the conference is not possible as in this case the total number of experts in population studies is 5. i.e., 2 from Australia, 1 from Asia, 1 from North America and 1 from the Latin America.

∴ This is not possible. The correct option is (d).

Answers 4: (d) For the common solution for this set, refer to solution of Question 1.

Number of labour experts from the Latin America = 1

Number of health experts from North America = 1

Number of health experts from Australia = 1

Number of experts in refugee relocation from Asia = 2/1

The correct option is (d).
