Solution

$20, 15, 25, 7, 25, 17, 5$
Arranging in descending order
$25, 25, 20, 17, 15, 7, 5$
$M e a n = \frac{s u m o f o b s e r v a t i o n s}{n u m b e r o f o b s e r v a t i o n s}$
$= \frac{25 + 25 + 20 + 17 + 15 + 7 + 5}{7}$
$= \frac{114}{7}$
$= 16.29$
Median $= (\frac{n + 1}{2}) t h o b s e r v a t i o n$
$= (\frac{7 + 1}{2}) t h o b s e r v a t i o n$
$= 4 t h o b s e r v a t i o n$
$= 17$
$M o d e = 25$

The relation between mean,mode and median is

(a) $m o d e = (3 \times m e a n) - (2 \times m e d i a n)$

(b) $m o d e = (3 \times m e d i a n) - (2 \times m e a n)$

(d) $m e a n = (3 \times m e d i a n) - (2 \times m o d e)$
