PSLE
A group of students was asked to choose one spaghetti set from tuna, turkey, chicken and vegetarian. 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 tuna spaghetti sets?

Spaghetti Sets	Students
Tuna	50%
Turkey	15%
Chicken	5%
Vegetarian	30%

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 = 20

5% of students = 20

1% of students = 20 ÷ 5 = 4

Percent of students who chose tuna spaghetti sets = 50%
Percent of students who chose turkey spaghetti sets = 15%

Percent of students who chose tuna and turkey spaghetti sets
= 50% + 15%
= 65%

Total number of students who chose chicken and tuna spaghetti sets
= 65 x 4 
= 260

Answer(s): 260
