There were twice as many 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?

সঠিক উত্তর: Option D
Let, Boys = 100, Girls = 200
200×30% + 100×45% = 60+45 = 105
{(300-105)/300}×100% = (195/300)×100% = 65% Ans.
