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

Sandwiches	Students
Tuna	5%
Hotdog	40%
Chicken	15%
Vegetarian	40%

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

Number of students who chose tuna sandwiches = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose tuna sandwiches = 5%
Percent of students who chose chicken sandwiches = 15%

Percent of students who chose tuna and chicken sandwiches
= 5% + 15%
= 20%

Total number of students who chose tuna and chicken sandwiches
= 20 x 2
= 40

Answer(s): 40
