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

Burgers	Students
Beef	5%
Hotdog	40%
Tuna	25%
Mutton	30%

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

Number of students who chose beef burgers = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose beef burgers = 5%
Percent of students who chose tuna burgers = 25%

Percent of students who chose beef and tuna burgers
= 5% + 25%
= 30%

Total number of students who chose beef and tuna burgers
= 30 x 2
= 60

Answer(s): 60
