PSLE A group of students was asked to choose one sandwich from chicken, beef, hotdog and mutton. 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 hotdog and chicken sandwiches?
Sandwiches |
Students |
Chicken |
65% |
Beef |
5% |
Hotdog |
15% |
Mutton |
15% |
Number of students who chose beef sandwiches is the least. So it is represented by the shortest bar.
Number of students who chose beef sandwiches = 10
5% of students = 10
1% of students = 10 ÷ 5 = 2
Percent of students who chose hotdog sandwiches = 15%
Percent of students who chose chicken sandwiches = 65%
Percent of students who chose hotdog and chicken sandwiches
= 15% + 65%
= 80%
Total number of students who chose beef and mutton sandwiches
= 80 x 2
= 160
Answer(s): 160
