D20 percent less
Correct answer: (A) 25 percent less — Males in City A are 5 by 8 of 64000, which is 40000.
Explanation
★Males in City A are 5 by 8 of 64000, which is 40000.
★Males in City B are 5 by 9 of 54000, which is 30000.
★City B has 10000 fewer males than City A.
★The percentage change relative to City A is 10000 divided by 40000 times 100.
★This equals 25 percent, and since B is smaller, it is 25 percent less.
★Percentage comparison is always taken with respect to the reference value named in the question.
★Here City A is the base, so its figure sits in the denominator.
