Question


How many "Rank 1" votes did West Indies get?


Options:
A .   83
B .   82
C .   81
D .   80
Answer: Option B
:
B

Let the number of "First Rank” votes of Australia and West Indies be equal to c and d respectively.


The "First Rank” votes of India, England. Australia and West Indies should add up to 350.


Therefore, 101 + 84 + c + d = 350 , c + d = 165 , c = 165 - d


Now, 84 > c > 165 - c


Therefore c = 83 and d = 82. Hence, (b)


After the second round of counting,


India's vote - count = India's "First Rank” votes + West Indies's "First Rank” votes that have India as "Second Rank” = 101 + 17 = 118


Let the number of West Indies's "First Rank” votes that have England and Australia as the "Second Rank” be x and y respectively.


Therefore, 17 + x + y = 82 y = 65 - x.


England's vote-count = England's "First Rank” votes + West Indies's "First Rank” votes that have England as the "Second Rank” = 84 + x.


Australia's vote-count = Australia's "First Rank” votes + West Indies's "First Rank” votes that have Australia as the "Second Rank” = 83 + y = 83 + 65 - x = 148 - x.


As India led while England was eliminated.


118 > 148 - x > 84 + x , x = 31.


Therefore, 31 of West Indies's "First Rank” votes have England as the "Second Rank”.
