Question

the mean of 100 number is 11 2.5 if each number is multiplied by 2 then new mean​

Answer 1

$Given ,Mean \: of \:100 \: numbers \: is \: 112.5$

if each number is multiplied by 2 then

$New \: mean = 2 \times (old \: mean )$

$= 2 \times 112.5$

$= 225$

Therefore.,

$\red{ Required \: mean } \green { = 225}$

Answer 2

Answer:

$\huge{ \bold{ \boxed{ \underline{ \mathfrak{ \star{ \green{ \orange{ \red{ \pink{ \blue{ \purple{ \red{ \mathfrak{a}{} }{n} }{s} }{w} }{} }{e} }{r} }{} }{} }{} }{} }{} }{} }{}$

$\sf{ \bold{ \blue{given \: }{} }{} }{}$

The mean of 100 numbers is 112.5

$\bf{ \green{to \: find \: }{} }{}$

The new mean multiplied by 2*

$\sf{ \purple{solution \: }{} }{}$

The given number of mean of 100 numbers is 112.5

So lets Multiply the numbers by 2.

New mean we obtain = 2*(old mean)

So, the new mean = 2*112.5

So, the new mean = 225

$\sf{ \bold{ \pink{so \: the \: new \: mean \: = 225}{} }{} }{}$
