CAT 2004 — DILR Question 28
Answer the following question based on the information given below.
Twenty one participants from four continents (Africa, Americas, Australasia, and Europe) attended a United Nations conference. Each participant was an expert in one of four fields, labour, health, population studies, and refugee relocation. The following five facts about the participants are given.
a. The number of labour experts in the camp was exactly half the number of experts in each of the three other categories.
b. Africa did not send any labour expert. Otherwise, every continent, including Africa, sent at least one expert for each category.
c. None of the continents sent more than three experts in any category.
d. If there had been one less Australasian expert, then the Americas would have had twice as many experts as each of the other continents.
e. Mike and Alfanso are leading experts of population studies who attended the conference. They are from Australasia.
Alex, an American expert in refugee relocation, was the first keynote speaker in the conference. What can be inferred about the number of American experts in refugee relocation in the conference, excluding Alex?
i. At least one
ii. At most two
Answer & solution
- A
Only i and not ii
- B
Only ii and not i
Both i and ii
- D
Neither i nor ii
Since Africa has 4 experts in total and none of them are from labour, the number of experts from the other 3 fields should be 4.
Hence, Africa’s Refugee Relocation experts ≤ 2
The total number of Refugee Relocation experts in the conference was 6. Of these, 1 is from Europe and 1 is from Australasia.
Hence, Refugee Relocation experts from Africa and Americas = 4
Hence, Total number of Refugee Relocation experts from Americas = 2 or 3
∴ Apart from Alex, there is at least one more and at most 2 more American experts in refugee relocation.
Hence, option (c).
