Answer 2

Answer:

12

Step-by-step explanation:

total no of students =11

failed students=3

let failed students be x1 , x2 , x3

passed students =8

now arrange all the marks of students in assending order

x1,x2,x3,10,11,12,14,15,20,24,26

if 'n' is odd median = middle most term of order

or

n+1 /2 th term

Therefore 11+1/2 = 6th term

thar is 12
