Given data is :

Below 10 — 0<hr> Below 20 — 12<hr> Below 30 — 20<hr> Below 40 — 28<hr> Below 50 — 33<hr> Below 60 — 40<hr>
To find the median , convert into class intervals with cf as :
0 -10 — 0 — 0<hr> 10-20 — 12 — 12<hr> 20-30 — 8 — 20<hr> 30-40 — 8 — 28<hr> 40-50 — 5 — 33<hr> 50-60 — 7 — 40<hr> Σf = 40
Now apply the formula of median :
Median = l + (n/2 - cf)/f ×h
=> 30 + (20 -20)/8 × 10
=> 30 + 0 = 30
