PSLE
A group of students was asked to choose one burger from tuna, chicken, hotdog and turkey. 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 hotdog and tuna burgers?

Burgers	Students
Tuna	10%
Chicken	40%
Hotdog	5%
Turkey	45%

Number of students who chose hotdog burgers is the least. So it is represented by the shortest bar.

Number of students who chose hotdog burgers = 20

5% of students = 20

1% of students = 20 ÷ 5 = 4

Percent of students who chose tuna burgers = 10%
Percent of students who chose chicken burgers = 40%

Percent of students who chose tuna and chicken burgers
= 10% + 40%
= 50%

Total number of students who chose hotdog and tuna burgers
= 50 x 4 
= 200

Answer(s): 200
