Answer 1

Step-by-step explanation:

Mean of 100 students =30

Mean of 100 students =30Mean of 50 students =60

Mean of 100 students =30Mean of 50 students =60Mean of 150 students =

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 =

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 150

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 =

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 = 150

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 = 1506000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 = 1506000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 = 1506000

Mean of 100 students =30Mean of 50 students =60Mean of 150 students = 150100∗30+50∗60 = 1503000+3000 = 1506000 =40
