A

9

B

10.5

C

12.67

D

14.76

Text Solution

Verified by Experts

The correct Answer is:
C
Marks obtained by 9 students in Mathematics are : 50, 69, 20, 33, 53, 39, 40, 65, 59
Let us reqrite the given data in ascending order.
20, 33, 39, 40, 50, 53, 59, 65, 69,
Here, n=9
Median `(M_(e ))`=5th term =50

`M.D. =(114)/(9)=12.67`
