Final answer:

The value of x is 36%, so the correct answer is C. 36≤x≤60. To find the value of x, use the concept of sets and the formula for finding the intersection of two sets.

Step-by-step explanation:

To find the value of x, we need to use the concept of sets and the formula for finding the intersection of two sets.

We know that 60% of the people watch one news channel, 76% watch another channel, and x% watch both channels. So the total percentage of people who watch at least one channel is given by:

Total percentage = Percentage watching first channel + Percentage watching second channel - Percentage watching both channels

Plugging in the given values, we get:

Total percentage = 60% + 76% - x%

Simplifying further:

Total percentage = 136% - x%

Since the total percentage cannot exceed 100%, we have:

100% = 136% - x%

Solving for x, we find:

x% = 36%

Therefore, the value of x is 36%, so the correct answer is C. 36≤x≤60.
