Solution

The correct option is A 12
Given that the numbers 50, 42, 35, (2x+10), (2x-8), 12, 11, 8 are in descending order.
Since, there are 8 terms in the given set, so the median will be the average of 4th and 5th terms.
Here, the 4th term is 2x+ 10 and 5th term is 2x-8.
Median = (2x+10)+(2x8)2
= (4x+2)2
= 2x + 1
Given, median of the data is 25
2x + 1= 25
2x = 24
x = 12
