There were twice as many girls as boys in a class. If 30% of the girls and 45% of the boys have already handed over their reports, what percent of the students have not yet done so?

Let, boys =x

and, girls = 2x

Total students = 3x

The amount of students handed over reports = 30% of 2x+ 45% of x= 0.6x+.45x=1.05x

Who have not done yet = (3-1.05)x=1.95x

The percentage of them = (1.95x/3x)×100=65 % (ans)
