Minimum 20 Students are their in a group

Answer 2

Answer:

Step-by-step explanation

Let total number of students be x

Therefore

Students who know hindi=1/2x

Students who know English=2/3x

Students who know both Hindi and English =10

Students who know only hindi =1/2x-10

Students who know only English =2/3x-10

Students who know neither of them =6

Therfore total number of students =

x=(1/2x-10)+(2/3x-10)+10+6

x=1/2x+2/3x-4

x=(3x+4x-24)/6

6x=7x-24

X=24
