During an experiment, the temperature of a liquid was measured several times. The temperatures, in degree Celsius, listed in increasing order, are 21, 25, x, 40 and 50. If the arithmetic mean of these temperatures is equal to the median, what is the value of x?

Option A:

34

Option B:

35

Option C:

36

Option D:

37

Option E:

38

Option A is the correct answer.

Given that Average = Median

Median is the middle most term in the ordered list

Average = total / number of things

(136+x)/5 = x

136+x = 5x

4x = 136

x = 34
