$avarage \: is \: 25$

$\frac{20 + 24 + 32 + x + 16 + 30}{2} = 25 \\ \frac{44 + 48 + 30 + x}{2} = 25 \\118 + x = 50 \\ x = - 68$

Answer 2

Answer:

we know that..,

average = sum of total observation / no. of total observation

Here..,

Average = 20+24+32+16+x+30/6

25 = (122 + x)/6

25*6= 122 + x

150- 122 = x

so, x = 28
