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? "**
