PSLE
A group of students was asked to choose one noodle set from hotdog, chicken, 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 hotdog noodle sets?

Noodle Sets	Students
Hotdog	25%
Chicken	25%
Vegetarian	5%
Mutton	45%

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 = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose hotdog noodle sets = 25%
Percent of students who chose chicken noodle sets = 25%

Percent of students who chose hotdog and chicken noodle sets
= 25% + 25%
= 50%

Total number of students who chose vegetarian and hotdog noodle sets
= 50 x 2 
= 100

Answer(s): 100
