Correct option is C. The number of votes cast for Pérez = 45,000
Let the common ratio be ′ x ′
As Garcia won against Prez by a ratio of 5 to 3,
Number of votes cast for Garcia = 5x
Number of votes cast for Prez = 3x
To find ′ x ′ ,
Total number of votes cast = Number of votes cast for Garcia + Number of votes cast for Prez
= 5x + 3x
= 8x
But, Given that
Total number of votes cast = 120,000
From above,
8x = 120,000
8 × x = 120,000
x = 120,000 / 8
x = 15,000
Now, number of votes cast for Prez = 3x
= 3 × x
= 3 × 15,000
= 45,000
Therefore, the number of votes cast for Prez was 45,000
