Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Total number of votes are 7500.
Number of valid votes are 80%.
Or we can say (80 / 100) x 7500 = 6000.

Candidate One got 45% of the total valid votes.
So, Other valid votes got by other candidate is (100% – 45%) = 55%.

So, the other candidate got,
(55 / 100) × 6000 = 3300 votes.
The total number of valid votes by the other candidate got is 3300.
