Answer 2

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• 15, 20, 25, 30, 35

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Average of the given data

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

• 15, 20, 25, 30, 35

• Average = ?

$\boxed{\pink{\sf Average \: = \: \dfrac{Sum \:of\: the\: given\: observations}{Total \:number \:of \:observations}}}$

• Total number of the observations = 5

$\sf Average \: = \: \dfrac{15 \: + \: 20 \: + \: 25 \: + \: 30 \: + \: 35}{5}$

$\sf Average \: = \: \dfrac{125}{5}$

$\sf Average \: = \: \dfrac{\cancel{125}}{\cancel{5}}$

$\sf Average \: = \: 25$

Therefore,

• $\underline{\boxed{\blue{\sf Average \: of \: the \: given \: data \: = \: 25.}}}$

Note:-

• Average or Mean both mean the same.
