If the number of votes increased by 600 percent from 2019 to 2023 and 76 percent of the votes were valid in 2023, then the number of valid votes polled in 2023 was
A5320 ✓ Correct
B5040
C5410
D4560
Correct answer: (A) 5320
Explanation
The number of valid votes in 2023 is 5320, so the answer is 5320.
The votes polled in 2019 were 1000.
A 600 percent increase multiplies this by 100 plus 600 over 100, which is 7.
So the votes polled in 2023 are 1000 times 7, which is 7000.
Of these, 76 percent are valid.
So the valid votes are 7000 times 76 over 100.
That equals 5320.
