PSLE
A group of students was asked to choose one spaghetti set from mutton, turkey, beef and egg. The table represents the students' choices. The students' choices were also represented by a bar graph but the names of the spaghetti sets were not shown. What was the total number of students who chose beef and mutton spaghetti sets?

Spaghetti Sets	Students
Mutton	40%
Turkey	20%
Beef	15%
Egg	25%

Number of students who chose beef spaghetti sets is the least. So it is represented by the shortest bar.

Number of students who chose beef spaghetti sets = 60

15% of students = 60

1% of students = 60 ÷ 15 = 4

Percent of students who chose mutton spaghetti sets = 40%
Percent of students who chose turkey spaghetti sets = 20%

Percent of students who chose mutton and turkey spaghetti sets
= 40% + 20%
= 60%

Total number of students who chose beef and mutton spaghetti sets
= 60 x 4 
= 240

Answer(s): 240
