PSLE A group of students was asked to choose one burger from hotdog, vegetarian, egg and beef. The table represents the students' choices. The students' choices were also represented by a bar graph but the names of the burgers were not shown. What was the total number of students who chose egg and hotdog burgers?
Burgers |
Students |
Hotdog |
10% |
Vegetarian |
45% |
Egg |
5% |
Beef |
40% |
Number of students who chose egg burgers is the least. So it is represented by the shortest bar.
Number of students who chose egg burgers = 20
5% of students = 20
1% of students = 20 ÷ 5 = 4
Percent of students who chose hotdog burgers = 10%
Percent of students who chose vegetarian burgers = 45%
Percent of students who chose hotdog and vegetarian burgers
= 10% + 45%
= 55%
Total number of students who chose egg and hotdog burgers
= 55 x 4
= 220
Answer(s): 220
