In an election between two candidates, 12% of voters did not cast their votes. The winner by obtaining 68% of the total votes defeated his contestant by 2880 votes. What was the total number of voters who cast their votes in the election?

5280

Let total voters be 100x

So, total voters who casted their vote = 88x

Now,

Winner got 100x × 68%

= 68a

So, losing candidate got 88x - 68x

= 20x

According to the question,

68x - 20x = 2880

= 48x = 2880

= x = 60

So, number of voters who casted their votes = 60 × 88

= 5280
