There are 7500 total votes. Of these 20% were invalid. This means that 80% were valid.
Multiplying 7500 by 80% gives us 6000 valid votes.
Since 55% of the 6000 valid votes were won by one candidate, that candidate got 6000 x 55%, or 3300 votes.
But the question is how many did the other candidate get. You can get this by multiplying the 6000 by 100"55 or 45% of the vote, or simply subtracting 3300 from 6000 which is 2700 votes.

100% votes =7500,
then loser percentage is 36% so we can calculate ( 36 * 7500)/100.

Invalid is 20%.
So, valid is (100 - 20) is 80%.
Total votes are 7500.
But we need to count only the valid ones.
So its 80% of 7500.
Which is 6000.
Now already 55% of 6000 is acquired by the 1st candidate.
So 100 - 55 which is 45% is for the other candidate.
Therefore, 45% of 6000.
45/100 * 6000 = 2700.
So, valid is (100 - 20) is 80%.
Total votes are 7500.

Base value 100% the invalid votes are 20% so the valid votes are 80% next one got 55%.
So, 55% of 80% = 44%.
The winner is 44% and the loser is 36%. The question is the total no of other candidates,
36% = x( unknown value)
100% = 7500(total votes), cross multiple
X*100 =36 * 7500.
So, x is 2700.
So, 55% of 80% = 44%.
The winner is 44% and the loser is 36%. The question is the total no of other candidates,
36% = x( unknown value)
100% = 7500(total votes), cross multiple
X*100 =36 * 7500.
So, x is 2700.

Valid vote for A = 55/100.
Number of valid votes = 80 * 7500/100 = 6000,
Valid votes pooled by A = 55 * 6000/100 = 3300,
So, 6000 - 3300 = 2700.
Number of valid votes = 80 * 7500/100 = 6000,

It asked to calculate the total number of valid votes that the winning candidate got.
So 1st person got 55% of total valid votes.
2nd person got 45% total valid votes.
So according to question 1st person should be winning right? because he has 55% votes more than 2nd.
In the question, it is nowhere mentioned that we have to calculate the total no of valid votes of 2nd candidate.
So how can the answer be 2700? Please explain me.

So, here lets us consider total votes be 100%.
So, remove invalid votes i.e 20 per hen we get 80 per valid votes.
Now in 80 per there are 55 per are valid votes so,
55/100*80=44 we get for one person,
In question, they mention other person valid votes so 80-44=36
100% = 7500(they are given).
36% = x,
X = 7500 * 36/100.
We get 2770 as final.

Total votes = 7500
Invalid votes = 20%
=>20/100 * 7500
= 1500.
Valid votes = 7500-1500 => 6000,
55% of 6000= 3300,
45%(other candidate)= 6000- 3300,
= 2700.
