Question

Out of 80 students in a school bus, 65% were boys.
If 25% of the girls wore spectacles, how many girls
did not wear spectacles?
​

Answer 1

Answer:

21

Step-by-step explanation:

Total students=80

No. of girls=80×35/100

=28

25% wore spectacles...So, 75% did not wear spectacles

That is; 28×75/100

=21

Answer 2

Answer:

first , the 65% of 80 students =52 students

(80×65÷100=52)

then, (80-52=28)

so, the total no. of girls in bus is 28

now, 25% of 80=20

(80×25÷100=20)

so, if 20 girls wear spectacles then left 8 did not wear spectacles.

so, the ans is 8 girls
