Answer:
70
Step-by-step explanation:
let the total students be 100
given that girls make 60%of students in school,
i.e,60 girls
out of 60 girls,2/3 girls prefer pens that means 40girls prefer pens
out of 40 boys,3/4 boys prefer pens that means 30boys prefer pens
therefore total percent of students prefer pens is {(40+30)/100}*100
=70percent of students prefer pens
