PSLE
A group of students was asked to choose one spaghetti set from egg, beef, turkey 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 turkey and egg spaghetti sets?

Spaghetti Sets	Students
Egg	15%
Beef	30%
Turkey	5%
Mutton	50%

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

Number of students who chose turkey spaghetti sets = 15

5% of students = 15

1% of students = 15 ÷ 5 = 3

Percent of students who chose egg spaghetti sets = 15%
Percent of students who chose beef spaghetti sets = 30%

Percent of students who chose egg and beef spaghetti sets
= 15% + 30%
= 45%

Total number of students who chose turkey and egg spaghetti sets
= 45 x 3 
= 135

Answer(s): 135
