Fruits	$30-40$	$40-50$	$50-60$	$60-70$	$70-80$	$80-90$	$90-100$
Boxes	$1$	$3$	$6$	$7$	$8$	$5$	$7$

• A. $70-80$
• B. $50-60$
• C. $40-50$
• D. $80-90$

Answer 1

The correct option is A $70-80$

$Class$ $Frequency$ $c.f$ $30-40$ $7$ $7$ $40-50$ $5$ $12$ $50-60$ $8$ $20$ $60-70$ $7$ $27$ $70-80$ $6$ $33$ $80-90$ $3$ $36$ $90-100$ $1$ $37$ $N=37$

$\Rightarrow$ Here $N=37$, so $\frac{N}{2}=\frac{37}{2}=18.5$

$\therefore$ Median class=50-60
