In an election between two candidates, one got 55% of the total valid votes, 20% of the votes were invalid. If the total number of votes was 7500, what was the number of valid votes that the other candidate got?
Choose one.
A) 2800 B) 2700 C) 2100 D) 2500 E) None of these
Explanation :   Total number of votes = 7500   Given that 20% of Percentage votes were invalid   =&gt; Valid votes = 80%   Total valid votes = 7500 × (80/100)   1st candidate got 55% of the total valid votes.   Hence the 2nd candidate should have got 45% of the total valid votes   =&gt; Valid votes that 2nd candidate got = total valid votes × (45/100)   = 7500 × (80/100) × (45/100) = 75 × 45 × 45 = 75 × 4 × 9 = 300 × 9 = 2700   Answer : Option 2700
