1. 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?
- A. 25
- B. 25
- C. 25
- D. 25
Answer: Option D
Explanation:
Let, Boys = 100
Girls = 200
200 × 30% + 100 × 45%
= 60 + 45
= 105
300 - 105 /300 × 100%
= 195 / 300 × 100%
= 65%
