Question

if the median of following is 20,then find the value of x 19,x,16,18,22,17,24,23,21

Answer 1

Answer:

x = 20

Step-by-step explanation:

Given that-

Median = 20

Numbers = x, 19, x, 16, 18, 22, 17, 24, 23, 21

Total numbers = 10

Using formula-

$Median = \dfrac{Sum \ of \ all \ numbers}{Total numbers}$

$20 = \dfrac{x+19+x+16+18+22+17+24+23+21}{10}$

$20 = \dfrac{2x+ 160}{10}$

$20 \times10 = {2x+160}$

200 = 2x + 160

2x = 200 - 160

2x = 40

x = 20
