anyone can solve then plz

Answer 1

x|0-50|50-100|100-150|150-200|200-250
f|10||||||20||||||||||30|||||||||||15|||||||||||||||15
CF|10||30||||||||||60||||||||||75||||||||||||||||90
total=90
n/2=90/2=45
so l¹=100,CF=30,f=30 ,i=50
median=l¹+{(n/2-cf)/f}×i
median=100+{(45-30)/30}×50
median=100+25=125
