∑f=N =60

Median class is given by the size of the N2th item, i e the 602th
item, which is the 30th item
This corresponds to the class interval 40-50, so this is the median
class
Median M=l1+N2-c
ff×i⇒Median M=40+602-2515×10⇒Median M=40+5015⇒Median (M)=43

Item (X)	Frequency (f)	Cumulative Frequency (c.f)
10 $-$ 20	6	6
20 $-$ 30	9	15
30 $-$ 40	10	25
40 $-$ 50	15	40
50 $-$ 60	12	52
60 $-$ 70	8	60
	$\sum f = N = 60$
