Answer 1

144^ as theThe persons of O- blood group are 40%.classification of persons based on blood groups is to be shown by a pie diagram

Answer 2

The persons of O- blood group are 40%. The classification of persons based on blood groups is to be shown by a pie diagram.

in a pie diagram

100% = 360 deg

as it is a complete circle

100% data is represented by 360 deg

1% data is represented by 360/100 = 3.6 deg

40% data is represented by = 3.6×40= 144 deg

o blood group data = 40% so

measures of angle for the persons of O- blood group = 144 deg

hence option D is correct

(D) 144°
