PSLE A group of students was asked to choose one sandwich from vegetarian, chicken, hotdog and tuna. 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 vegetarian and hotdog sandwiches?
Sandwiches |
Students |
Vegetarian |
5% |
Chicken |
30% |
Hotdog |
15% |
Tuna |
50% |
Number of students who chose vegetarian sandwiches is the least. So it is represented by the shortest bar.
Number of students who chose vegetarian sandwiches = 20
5% of students = 20
1% of students = 20 ÷ 5 = 4
Percent of students who chose vegetarian sandwiches = 5%
Percent of students who chose hotdog sandwiches = 15%
Percent of students who chose vegetarian and hotdog sandwiches
= 5% + 15%
= 20%
Total number of students who chose vegetarian and hotdog sandwiches
= 20 x 4
= 80
Answer(s): 80
