Answer:

k

Explanation:

Answer:

option A

Explanation:

given,                                  

increasing order                        

21,  25,  x,  40,    50              

median of the given number = x

Mean of the temperature = mean              

mean = [tex]\dfrac{21+25+x+40+50}{5}[/tex]

x = [tex]\dfrac{21+25+x+40+50}{5}[/tex]

5 x = 136 + x

4 x = 136                                                

[tex]x = \dfrac{136}{4}[/tex]

x = 34

correct answer is option A
