Answer:
51.7 median
hope it helps
Step-by-step explanation:
classes: c.f
more than 20 90+10=100
more than 30 82+8=90
more than 40 70+12=82
more than 50 46+24=70
more than 60 40+6=46
more than 70 15+25=40
more than 80 15
median class= n/2 ie 100/2=50 so median class will be more than 50 class
median =50+[(50-46)/24]×10=50+1.7 ie 51.7
