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, the number of valid votes that the other candidate got, was:
2700
2900
3000
3100
Answer: Option
Explanation:

Number of valid votes = 80% of 7500 = 6000.

Valid votes polled by other candidate = 45% of 6000

= 45 x 6000 = 2700.
100

Here in this context 55% and 20% of valid and invalid votes is considered for one candidate. Then how could we consider for the total valid and invalid percents?

Please explain.

They are asking for valid votes.


Valid votes are 80% which is equal to 6000. In these 6000 votes A got 55% and the remaining valid votes are 25%. So the answer is 25% of 6000.

In the question is asking how many valid votes did the other candidate got so 20%are invalid means 80% so it should be 80-55=25.

Or not because its talking bout valid votes?

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.

Try this method

Invalid votes = 20*7500/100=1500
Total Valid Votes = 7500-1500=6000
Candidate A got 55*6000/100=3300
Candidate B valid votes = 6000-3300=2700

@All.

(100-20)% = 80% of valid votes.
80/100*7500 = 6000,

Then for one candidate it is 55% question for other so,(100-55)% = 45%,
So,
45/100 * 6000 = 2700.

How came 45%.
As invalid votes are 20% we get 80% valid votes.

55% for one candidate then only 25% for other voter that are valid.

Can anyone explain it?

As per the question:

55% out of valid vote which is 80% (since 20% vote is invalid)
Therefore, 80% - 55% = 25% (valid vote left)
So, 25/100 * 6000 = 1500.

55% of votes to one person and 20% are invalid votes 55% + 20% = 75%. Other person get 25% votes. Why 45%, why don't removed those 20% votes from 100%?
