Question

if the mode and median of n observation are 1400 and 1500 respectively find its mean

Answer 1

$\Longrightarrow{\boxed{\bold{Answer:1550}}}$

$\textbf{\underline{Step-by-step explanation :- }}$

➣ Since we know that,

3Median - 2mean = Mode

➣ Here,

Median = 1500

And Mode = 1400

➣ Let's substitute the values,

⇒3( 1500 ) - 2Mean = 1400

⇒4500 - 2Mean = 1400

⇒4500 - 1400 = 2Mean

⇒3100 = 2Mean

$\textbf{\huge{\underline{1550 = Mean}}}$

Answer 2

$\huge{\mathfrak{\underline{\underline{ANSWER}}}}$

Hey ==>

given==> mode = 1400

median = 1500...

mean (n) = ?

we have the relationship

mean × 2 = 3 median - mode..

mean × 2 = 3 (1500) - 1400

mean × (2) = 4500 - 1400

mean × (2) = 3100

mean = 3100$\frac{1}{2}$

mean = 1550....
