Question

Calculate the mean where mode and median are given as $25$ and $30$.

• A. $22.5$
• B. $12.5$
• C. $32.1$
• D. $32.5$

Answer 1

The correct option is D $32.5$

We know that $mode=3median-2mean$

Given that $mode=25$ and $median=30$

Therefore, $25=3\left(30\right)-2mean$

$⟹2mean=90-25$

$⟹mean=\frac{65}{2}=32.5$
