    D 52,560 Correct Answer Incorrect Answer

    Solution

    Let the number of voters be 500 No. of voters promised to vote for Modi = 2/5 × 500 = 200 No. of voters promised to vote for Kejriwal = 3/5 × 500 = 300 No. of voters who went back(15%) = 15/100 × 200 = 30 No. of voters who went back(25%) = 25/100 × 300 = 75 Total votes for Modi = 200 – 30 + 75 = 245 Total votes for Kejriwal = 300 + 30 - 75 = 255 Difference of voters = 255 – 245 = 10 ∴ Total no. of voters = (850 ×500)/10 = 42,500
