Show answer & explanation

Correct answer: C

Explanation

 The correct answer is option 3 i.e. 15625.

Given that

In an election between two candidates, 80% of the voters cast their votes, out of which 5% votes were declared invalid

A candidate got 9500 votes which were 80% of the valid votes

Let the total number of votes = 100x

According to the question

The number of casting votes = 80% × 100x = 80x

The number of valid votes = 80x × 95/100 = 76x

Now, 

80% of the valid votes = 9500

(80/100) × 76x = 9500

x = 156.25

100x = 156.25 × 100 = 15625

Hence, the total number of voters enrolled in that election is 15625
