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

Noodle Sets	Students
Tuna	50%
Turkey	15%
Vegetarian	10%
Mutton	25%

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

Number of students who chose vegetarian noodle sets = 30

10% of students = 30

1% of students = 30 ÷ 10 = 3

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

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

Total number of students who chose vegetarian and tuna noodle sets
= 65 x 3 
= 195

Answer(s): 195
