VALID 55% 45%
INVALID 20% 80%
45%/125% * 100 = 2700.

Invalid votes are 20%.
So total votes 7500*20/100 = 6000.
Another candidate elected 55%.
Remaining percentage are 45%.
= 6000*45/100 = 2700.
So total votes 7500*20/100 = 6000.
Another candidate elected 55%.
Remaining percentage are 45%.
= 6000*45/100 = 2700.

Total number of votes = 7500.
Number of invalid votes = 20/100*7500 = 1500 (i.e. 20% of total votes).
Number of valid votes = 7500-1500 = 6000.
But one person got 55% of valid vote = 55/100*6000 = 3300.
And definitely, the other candidate will be left with = 6600-3300 = 2700.
The required answer will be 2700.

Friends, first let's calculate the % of valid votes:
20% = 1/5*7500 = 1500 invalid and valid will be 7500-1500 = 6000 valid votes.
Let's see the valid votes of the first candidate 55% of 6000.
= 55/100*6000 = 3300. So this is the first, do not confuse your self and think, we have 2 people one got 3300 out of 6000, so how many did the second get, 6000-3300 = 2700.
20% = 1/5*7500 = 1500 invalid and valid will be 7500-1500 = 6000 valid votes.

55% of 7500 = 4125.
20% of 7500 = 1500.
4125+1500 = 5625.
7500-5625 = 1875.
So 1875 is the correct answer.
20% of 7500 = 1500.
4125+1500 = 5625.
7500-5625 = 1875.
So 1875 is the correct answer.

Total votes = 7500 and 20% are invalid 7500*20/100 = 1500, and 7500-1500 = 5000, and 5000*55/100 = 2750.

Person A got 55% total valid votes but out of 55% he got 20% invalid votes.
So 55-20=35% valid votes he got.
Then 35% valid votes got by A+20% invalid votes got by A+45% valid votes got by B.
Now we calculate 20/100*7500 = 1500 invalid votes got by A.
Then total valid votes are = 7500-1500 = 6000.
35/100*6000 = 2100 valid votes got by A.
45/100*6000 = 2700 valid votes got by B.
2700 is the answer.
So 55-20=35% valid votes he got.
Then 35% valid votes got by A+20% invalid votes got by A+45% valid votes got by B.
Now we calculate 20/100*7500 = 1500 invalid votes got by A.
Then total valid votes are = 7500-1500 = 6000.
35/100*6000 = 2100 valid votes got by A.
45/100*6000 = 2700 valid votes got by B.
2700 is the answer.
