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

Noodle Sets	Students
Vegetarian	35%
Mutton	10%
Tuna	40%
Egg	15%

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

Number of students who chose mutton noodle sets = 20

10% of students = 20

1% of students = 20 ÷ 10 = 2

Percent of students who chose tuna noodle sets = 40%
Percent of students who chose vegetarian noodle sets = 35%

Percent of students who chose tuna and vegetarian noodle sets
= 40% + 35%
= 75%

Total number of students who chose mutton and egg noodle sets
= 75 x 2
= 150

Answer(s): 150
