PSLE A group of students was asked to choose one sandwich from egg, beef, chicken and turkey. 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 chicken and egg sandwiches?
Sandwiches |
Students |
Egg |
20% |
Beef |
20% |
Chicken |
10% |
Turkey |
50% |
Number of students who chose chicken sandwiches is the least. So it is represented by the shortest bar.
Number of students who chose chicken sandwiches = 20
10% of students = 20
1% of students = 20 ÷ 10 = 2
Percent of students who chose egg sandwiches = 20%
Percent of students who chose beef sandwiches = 20%
Percent of students who chose egg and beef sandwiches
= 20% + 20%
= 40%
Total number of students who chose chicken and egg sandwiches
= 40 x 2
= 80
Answer(s): 80
