Answer 1

$\huge \fcolorbox{green}{blue}{ \bf \red{P = 0}}$

Step-by-step explanation:

QUESTION :-

Find the value of P if mean of 20, 35, 30, P, 22, 13 is 20.

________________________

SOLUTION :-

We know that,

$\bf mean = \dfrac{sum \: of \: terms}{number \: of \: terms}$

So,

if we put the terms in the formula, the mean will be 20

$= > \bf \frac{20 + 35 + 30 +P + 22 + 13}{6} = 20 \\ \\ = > \bf20 + 35 + 30 + P + 22 + 13 = 20 \times 6 \\ \\ = > \bf 20 + 35 + 30 + 22 + 13 + P = 120 \\ \\ = > \bf 120 + P = 120 \\ \\ = > \bf P = 120 - 120\\ \\ = > \bf \underline \red{P = 0}$

So,

The value of P = 0.
