Question

The polling results show the ratio of votes for Candidate A to Candidate B.

Candidate A Candidate B
15 18
25 30
35 42
45 ?


At this rate, if Candidate A received 45 votes, how many votes did Candidate B receive?
54
56
60
90

Answer 1

• A) 54 votes

---------------------

We can see the ratio of A/B is same for the first three rows of the table:

• 15/18 = 5/6
• 25/30 = 5/6
• 35/42 = 5/6

Assume the same ratio applies to the last row, then:

• 45/x = 5/6
• x = 45*6/5
• x = 54

Correct choice is A.
