Question

2. The median of the following numbers arranged in ascending order is 25. Find the value of x.
4, 7, 10, 17, 2x + 1, 2x + 10, 37, 39, 48
​

Answer 1

Answer:

2x+1+2x+10

__________=25

2

4x+11=25

4x=25-11

4x=14

x=14/4=3.5

Answer 2

Answer:

here the number of observation is odd.

so,median=

Step-by-step explanation:

n+1/2th observation(where n means no.of observation(

=9+1/2th observation

=10/2=5th observation(equation 1)

but according to question,

median=25(equation 2)

from equation 1 and 2 we get

25=2x+1

26=2x

x=13

therefore the value of x is 13
