The pie chart below shows the favorite hobbies of 120 children.

The number of children who prefer cycling is 12.
Three times as many prefer football than the number who prefer cycling.
How many children prefer swimming?
A. 42
B. 52
C. 58
D. 40
E. 62

Answer 1

72 children prefer cycling

Explanation:

Cycling = 12 children

Football = (12×3) = 36 children

120 - (12 + 36) = 72

Answer 2

Answer is A. 42

We are given the following

120 children total
12 Children who like to cycle is given
36 Children who like football = 3 x 12 = 36
30 Children who like reading = 90 degree right angle divided by 360 total degrees of pie chart = 25% of pie chart like reading. We have a total of 120 children x 25% = 30
X unknown children who like swimming.

Total children less the 3 parts of the pie we know = unknown

120 - 12 - 36 - 30 = 42 children who like swimming
