Question

If the average of 14,17,21,26 and X is 20 What is the value of X​

Answer 1

Answer:

X= 22 ; ans.

Step-by-step explanation:

Average=Sum of observation/ No. of observation

20 = (14+17+21+26+x) / 5

20 = (78+x) / 5

20 × 5 = 78 + x

100 = 78 + x

x = 100-78

= 22 ; ans

Answer 2

The value of X is 22.

Given:

• If the average of 14,17,21,26 and X is 20.

To find:

• What is the value of X ?

Solution:

Concept /formula to be used:

$\bf Average = \frac{ \text{\bf Sum of all observations \:} }{ \text{\bf Total \: observations}}$

Step 1:

Write the values in the formula.

$20 = \frac{14 + 17 + 21 + 26 + X}{5}$

$100 = 14 + 17 + 21 + 26 + X$

$\bf 100 = 78 + X$

Step 2:

Find the value of X.

$X = 100 - 78$

$\bf X = 22$

Thus,

The value of X is 22.
