The angle of orange is unknown but can be found since the sum of all angles in a pie chart must be 360. That is,
let x be the unknow angle of orange
60 + 100 + 120 + x = 360
280 + x = 360
Subtract 280 from both sides
x = 360 - 280
x = 80
Thus, the angle of orange is 80o
Since the number of oranges is given as 60, we can find that of apple by comparing the angle and number of apples with that of orangle.
let y be the number of apples displayed
That is,
80o/60 = 120o/y
cross multiply,
80y = 60 x 120
80y = 7200
divide both sides by 80
y = 7200/80
y = 90
Therefore, there are 90 apples on display
