1. A class of 80 students has 25% girls. If 10% of the boys and 20% of the girls attended a picnic then what percentage of the class attended the picnic ?
- A. 20%
- B. 20%
- C. 20%
- D. 20%
Answer: Option D
Explanation:
25% of 80=20
So,
Girls=20
Boys=80-20=60
10% of 60=6
20% of 20=4
Total students=80, Students in picnic=6+4=10
Now,
(10×100)/80=12.5%
