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
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

Simple friends.
= 45 % ( 80 % 7500 )
= 2700
= 45 % ( 80 % 7500 )
= 2700

Valid votes are 55% and total votes are 7500. &20% are not valid so till 80% its correct but after that how you took 45%????? coz we should deduct 55% from 80% not from 100% because valid votes are 80% not 100% so accordingly, 2nd candidate would get only 25%

Why cant we do in this way?
First considering the valid votes 80%of 7500=6000, 1st person's votes are 55% so, 55% of 6000= 3300, now subtracting it from total valid votes we get the second persons votes=2900

Invalid vote= 20%*7500=1500.
Valid vote =7500-1500=6000.
Therefore, 45%*6000=2700 (since 100-55=45).
Valid vote =7500-1500=6000.

Invalid Vote 20%
So Valid Vote 100-20=80
55% of The Total Valid Vote=80*55/100=44 Rest [80-44]=36.
7500-7500*20/100=6000
Then 36/80*6000=2700 Answer.

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?
