PSLE
A group of students was asked to choose one spaghetti set from egg, hotdog, chicken and mutton. 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 chicken and egg spaghetti sets?

Spaghetti Sets	Students
Egg	30%
Hotdog	20%
Chicken	15%
Mutton	35%

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

Number of students who chose chicken spaghetti sets = 30

15% of students = 30

1% of students = 30 ÷ 15 = 2

Percent of students who chose egg spaghetti sets = 30%
Percent of students who chose hotdog spaghetti sets = 20%

Percent of students who chose egg and hotdog spaghetti sets
= 30% + 20%
= 50%

Total number of students who chose chicken and egg spaghetti sets
= 50 x 2 
= 100

Answer(s): 100
