In an election between two candidates 70% of the voters cast their votes, out of which 2% of the votes were declared invalid. A candidate got 7203 votes which was 60% of the total valid votes. Find the total number of voters enrolled in that election.

Let total number of votes enrolled = xNo. of voted cast = 70% of x = 0.7xValid votes = 98% of 0.7x⇒ 60% of total valid votes = 7203 = 60% of 98% of 0.7x⇒ 0.6 X 0.98 X 0.7x = 7203⇒ x = 7203 / (0.6 X 0.98 X 0.7)⇒ x = 17500
