The OA is C.
Please, can someone assist me with this DS question? Thanks in advance.
Given: 3/4 of the registered voters cast ballots
=> 1 - 3/4 = 1/4 of the registered voters who did not cast ballots
To find: Number of registered voters who cast ballots for the winning candidate
Let's take each statement one by one.
(1) 25000 registered voters did not cast ballots in the election.
=> 1/4 of the registered voters who did not cast ballots = 25000
=> Total number of registered voters = 100,000
Can't get the value of the number of registered voters who cast ballots for the winning candidate. Insufficient.
(2) Of the registered voters who cast ballots, 55 percent cast ballots for the winning candidate.
Votes to the winning candidate = 55% of 3/4 of the registered voters
We do not have the information about the number of the registered voters. Insufficient.
(1) and (2) together
Votes to the winning candidate = 55% of 3/4 of the registered voters = 55% of 3/4 of 100,000 = A unique value. Sufficient.
The correct answer:
C
Hope this helps!
