PSLE
A group of students was asked to choose one noodle set from egg, vegetarian, hotdog and beef. 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 hotdog and egg noodle sets?

Noodle Sets	Students
Egg	25%
Vegetarian	5%
Hotdog	20%
Beef	50%

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 = 20

5% of students = 20

1% of students = 20 ÷ 5 = 4

Percent of students who chose hotdog noodle sets = 20%
Percent of students who chose egg noodle sets = 25%

Percent of students who chose hotdog and egg noodle sets
= 20% + 25%
= 45%

Total number of students who chose vegetarian and beef noodle sets
= 45 x 4
= 180

Answer(s): 180
