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

Noodle Sets	Students
Vegetarian	75%
Tuna	5%
Chicken	10%
Mutton	10%

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

Number of students who chose tuna noodle sets = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose chicken noodle sets = 10%
Percent of students who chose vegetarian noodle sets = 75%

Percent of students who chose chicken and vegetarian noodle sets
= 10% + 75%
= 85%

Total number of students who chose tuna and mutton noodle sets
= 85 x 2
= 170

Answer(s): 170
