In a class, if 50% of the boys were girls, then there would be 50% more girls than boys. What percentage of the overall class is girls?
Explanation:
In the final state, the number of girls should be 1.5 * the number of boys.
When 50% of the boys are taken as girls, let the number of boys = x
Number of girls = 1.5x
Total number of students = 2.5x
Original number of boys = 2x (50% of boys = x)
Original number of girls = 0.5x
Girls form 20% of the overall class.
The question is " What percentage of the overall class is girls? "
Girls form 20% of the overall class.
Hence, the answer is 20%
Choice D is the correct answer.
