Answer 1

Answer:

There are 1200 students.

if there are 800 boys then there are (1200-800) 400 girls.

boys wearing spectacles =20%of 800

=160 boys

Girls wearing spectacles =25%of 400

= 100 girls

total wearing spectacles =160+100=260students

Answer 2

Answer:-

No. of total students = 1200

No. of boys = 800

No. of girls = 1200-800

= 400

No. of boys wearing spectacles = 20% of 800

=$\frac{20}{100} \times 800$

= 160

No. of girls wearing spectacles = 25% of 400

=$\frac{25}{100} \times 400$

= 100

Total no. of students wearing spectacles=160+100

= 260

Therefore, total 260 students wear spectacles
