If the mean of $20,14,16,19,p$ and $21$ is $27$ then find the value of $_{′}p_{′}$

Given numbers.

$20,14,16,19,p,21$

And mean of these numbers is $27$.

Since, total number $=6$.

Therefore,

$Mean=totalnumberssumoftotalnumbers $

$620+14+16+19+p+21 =27$

$90+p=162$

$p=72$

Hence, the value of $p$ is $72$.
