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%
