Hey!!

Good morning

First of all this is a raw data

Thus here n = 8(even)

Here we have a formula for even number of observations

The formula is

M =\frac{( { \frac{n}{2}) }^{th \: ob.} + {( \frac{n}{2} + 1)}^{th \: ob.} }{2} 2( 2n ) thob. +( 2n +1) thob.

So

here (n/2)th observation is 4th observation

and (n/2 + 1)th observation is 5th observation

Thus

M = (x + 2 + x + 3)/2

Thus

=> 27.5 = (2x + 5)/2

=> 2x + 5 = 55

=> 2x = 50

=> x = 25 <<<<<<<< Answer
