Answer 1

Answer:

3250

Step-by-step explanation:

students in school uniform (a) = 2/13

students in casual dresses (b) = 3/10

students in formal dresses (c) = 1/5

So,a+b+c= 6500

the no.of students who comes in formal and casual dresses (b+c)= 3/10 +1/5

= 5/10

= 1/2

therefore, 6500(1/2)= 3250
