In an election between two candidates, one got 40% of the total valid votes, and 30% of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got was:

3150

70% = \(\frac{7}{10}\) & 60% = \(\frac{3}{5}\)

Total number of votes = 7500

Total valid votes = 7500 × \(\frac{7}{10}\) = 5250

Valid votes that 2nd candidate got = total valid votes x  \(\frac{3}{5}\)

= 5250 × \(\frac{3}{5}\)

= 3150
