The favourite colours represent the following angles: red (90°), blue (90°),  green (135°) and yellow (45°).

Rule of Three

It's a math tool for solving problems about proportion. You can relate more than 2 variables and from the proportion, it's possible to find an unknown number.

Here you can apply the rule of three for finding the angle  of each frequency. The total of people (400) represents the total angle of a circumference which is 360°.

  • For colour - red

400 ----------- 360°

100 ------------ r

400r=360*100

400r=36000

r=36000/400

r=90°

  • For colour - blue

400 ----------- 360°

100 ------------ b

400b=360*100

400b=36000

b=36000/400

b=90°

  • For colour - green

400 ----------- 360°

150------------ g

400g=360*150

400g=54000

g=54000/400

g=135°

  • For colour - yellow

400 ----------- 360°

50------------ y

400y=360*50

400y=54000

y=18000/400

y=45°
