Correct Answer - Option 3 : 2700
Given:
A got 55% of valid votes
Total number of votes were 7500
20% votes were invalid
Calculation:
Total number of votes = 7500
20% of votes were invalid
⇒ Valid votes = 80%
Total valid votes = 7500 × (80/100)
A got 55% total valid votes
So, B should have got 45% of the total valid votes
⇒ Candidate B got = total valid votes × (45/100)
⇒ 7500 × (80/100) × (45/100) = 2700
∴ Candidate B got 2700 of total valid votes.
