Question

Workers in an office of 40 staff were asked their favourite take away. the results are summarised in the table.

PIZZA - frequency =3 angle = a
CURRY - frequency=12 angle =b
FISH AND CHIPS- frequency =7 angle =c
KABAB-frequency =3 angle = d
OTHER-frequency=15 angle = e

Answer 1

Pizza: 27°

Curry: 108°

Fish and Chips: 63°

Kabab: 27°

Other: 135°

Explanation:

Frequency 40 = 360°

Pizza (3) =
`(3)/(40)` * 360° = 27°

Curry (12) =
`(12)/(40)` * 360° = 108°

Fish and Chips (7) =
`(7)/(40)` * 360° = 63°

Kabab (3) =
`(3)/(40)` * 360° = 27°

Other (15) =
`(15)/(40)` * 360° = 135°

27 + 108 + 63 + 27 + 135 = 360
