In 55% votes only 35% of votes only valied therefore 35+45 is 80 to find total no of valid votes we do 80*7500/100

It is required to give total no.of valid votes instead of no.of votes, I got confused. Anyway, a nice question.

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.

Out of 100% votes 20% is invalid votes i.e. 100%-20%= 80% valid votes and 100-55%=45% other got these much.

No @Kuldeep, 20% are invalid. So 100 - 20 = 80% of valid votes. Why are you thinking of 85% of valid votes?

Easy solution is;.
(100-20)% of valid votes,
80/100*7500 = 6000,
45/100*6000 = 2700,
So, Ans= 2700 votes.
(100-20)% of valid votes,
80/100*7500 = 6000,
45/100*6000 = 2700,
So, Ans= 2700 votes.

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

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

@Shivani.
80% - (55% of 80).
=> (80 - {(55*80)/100} )%,
=> (80 - 44)%,
valid votes = 36%.
80% - (55% of 80).
=> (80 - {(55*80)/100} )%,
=> (80 - 44)%,
valid votes = 36%.

100X = 7500.
X = 75.
(100-20)X = 80X,
55% of 80X = 44X,
(80-44)X = 36X,
36X = 36 * 75 = 2700.
X = 75.
(100-20)X = 80X,
55% of 80X = 44X,
(80-44)X = 36X,
36X = 36 * 75 = 2700.
