Percentage
In an election between two candidates, one got 55% of the total valid votes. Twenty percent of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got was:
Explanation and memory cue
Total votes = 7500; invalid votes = 20% of 7500 = 1500; valid votes = 7500 - 1500 = 6000. One candidate got 55% of valid votes = 0.55 × 6000 = 3300. The other candidate got the remaining valid votes = 6000 - 3300 = 2700. However, 2700 is option A, but the question asks for the number of valid votes the other candidate got, which is 2700. The original correct_answer was A, which matches 2700, so the original answer is correct. The explanation was missing and is now provided. The difficulty is set to easy as it involves basic percentage calculations.
