Answer 1

$Given \: the \: distribution \:of \:demand \: of$

$an \: item \: on \: different \: days .$

$From \: the \: table \: above$

$\sum f_{i} = 50 , \: \sum f_{i}x_{i} = 1295$

$\boxed{ \pink{ Mean = \frac{ \sum f_{i}x_{i}}{\sum f_{i} } }}$

$= \frac{1295}{50}$

$= 25.9$

Therefore.,

$\red{ Mean \: demand } \green { = 25.9 }$
