UPSC CDS Math Percentage Questions

Let the total number of voters in the voters’ list be x.
Number of votes cast to the winner candidate = 47% of x
Number of votes cast to the losing candidate = (90% of x−60)-47% of x=43% of x−60
Number of votes cast to the winner candidate - Number of votes cast to the losing candidate = 308
∴ 47% of x - (43% of x - 60) = 308
⇒ 4% of x + 60 = 308

x=308−60=248
