Question

Numbers 2,3,5,6+x,9,10,15 are written in the ascending order.If There median is 7 what will be x?​

Answer 1

Answer:

Step-by-step explanation:

7

Answer 2

Answer:

The numbers are 6, 8, 10, 12, 13 and x

n = 6

Mean = (6 + 8 + 10 + 12 + 13 +x)/6

Mean = (49 + x)/6       …(i)

For median n = 6 (even)

Median = [(n/2)th term +( n/2 + 1)th term]/2

Median = (3rd term + 4th term)/2

= (10 + 12)/2

= 22/2 =11    …(2)

From (1) and (2)(from question)

Median = mean

11 = (49 + x)/6

⇒ x = 66 – 49

⇒ x =17
