ANSWER :—

$\:$

★ Mean :—

$\:$

$\bold \color{pink}{→ Mean = \frac{Sum \: of \: all \: observations }{Total \: number \: of \: observations} }$

$\:$

$\bold{→ Mean = \frac{(30 \times 5) + (34 \times 6) +( 38 \times 8) + (40 \times 10) + (45 \times 8) + (50 \times 3)}{6} }$

$\:$

$\bold{→ Mean = \frac{150 + 204 + 304 + 400 + 360 + 150}{6} }$

$\:$

$\bold{→ Mean = } \frac{1568}{6}$

$\:$

$\bold{→ Mean = 261.3}$

★ Median :—

$\:$

~Median means middle.

$\:$

38 and 40 are the middle numbers. So we will add 38 and 40 and then divide by 2 to get the exact median.

$\:$

$\bold{→ Median = \frac{38 + 40}{2} }$

$\:$

$\bold{→ Mean = \frac{78}{2} }$

$\:$

$\bold{→ Mean = 39}$

$\:$

.°. The median is 39.

★ Mode :—

$\:$

~Mode is the number with higher frequency.

$\:$

So when we look at the table we can see that 40 has the highest frequency.

$\:$

.°. 40 is the mode.
