Correct Answer - Option 1 : 25000
Given:
In an election between Shubham and Ravi only 80% of people participated in voting. 10% of the polled votes were declared invalid. Shubham gets 60% of total valid votes and he wins by 3600 votes.
Concept used:
Percentage
Calculation
Let the total votes be 100x
80% of people came for voting
so total voting is 80x votes
10% of polled votes is declared invalid
10% of 80 = 8x
Total valid votes 80x - 8x = 72x
Shubham gets 60% of total votes
60% of 100 = 60
Ravi gets 100 - 60 = 40 votes
Difference is 60 - 40 = 20%
20% of 72x = 3600
⇒ x = \(\frac{{3600\ ×\ 5}}{{72}}\)
∴ x = 250
Total votes = 250 × 100 = 25000
