Let number of male voters = 4x and female voters = 3x And, number of male who voted = (4x – 480) and number of female who voted = (3x - 460) According to the question, (4x – 480) ∶ (3x – 460) = 18 ∶ 13 ⇒ 52x – 6240 = 54x – 8280 ⇒ 2x = 2040 ⇒ x = 1020 ∴ Number of male who voted = 1020 × 4 – 480 = 3600
