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

@Manu
80/100*7500 = 6000
80/100*7500 = 6000

The answer rite.
First deduct the invalid 20% from the total 7500 =6000.
So the other candidate valid vote is 45/100*6000=2700 (since 55-100=45).
First deduct the invalid 20% from the total 7500 =6000.
So the other candidate valid vote is 45/100*6000=2700 (since 55-100=45).

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

There is another method we can apply :
The total % of invalid vote is 20% i.e. 100-20 = 80
therefore, out of 100%, 80% vote are valid vote.
so, the first candidates got 55% of 80. i.e. 44.
and the second candidates got 80-44 = 36.
therefore, 36/100*7500 = 2700.
The total % of invalid vote is 20% i.e. 100-20 = 80
therefore, out of 100%, 80% vote are valid vote.
so, the first candidates got 55% of 80. i.e. 44.
and the second candidates got 80-44 = 36.
therefore, 36/100*7500 = 2700.

We can also do it as ..
There is only 80% votes are valid so
80% of 7500 = 6000 are total valid votes
and one candidate got 55% of total votes i.e.6000*55/100=3300( votes of one candidate )
So other candidate got votes 6000-3300=2700 votes.
There is only 80% votes are valid so
80% of 7500 = 6000 are total valid votes
and one candidate got 55% of total votes i.e.6000*55/100=3300( votes of one candidate )
So other candidate got votes 6000-3300=2700 votes.
