Find the total number of voters, if Modi wins by 850 votes. Correct Answer 42500
GIVEN:
Voters who promised to vote for Rahul = 2/5
Voters who went back to their promise = 15% of the voters from Rahul side and 25% of the voters from Modi side
CALCULATION:
Let the number of voters be 500
Number of voters promised to vote for Rahul = 2/5 × 500 = 200
Number of voters promised to vote for Modi = 3/5 × 500 = 300
Number of voters who went back from voting in favor of Rahul (15%) = 15/100 × 200 = 30
Number of voters who went back from voting in favor of Modi (25%) = 25/100 × 300 = 75
Total votes for Rahul = 200 - 30 + 75 = 245
Total votes for Modi = 300 + 30 - 75 = 255
Difference of voters = 255 - 245 = 10
∴ Total no. of voters = (850 × 500)/10 = 42,500
