PSLE
A group of students was asked to choose one rice set from chicken, hotdog, beef and mutton. The table represents the students' choices. The students' choices were also represented by a bar graph but the names of the rice sets were not shown. What was the total number of students who chose beef and chicken rice sets?

Rice Sets	Students
Chicken	45%
Hotdog	35%
Beef	5%
Mutton	15%

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

Number of students who chose beef rice sets = 20

5% of students = 20

1% of students = 20 ÷ 5 = 4

Percent of students who chose chicken rice sets = 45%
Percent of students who chose hotdog rice sets = 35%

Percent of students who chose chicken and hotdog rice sets
= 45% + 35%
= 80%

Total number of students who chose beef and chicken rice sets
= 80 x 4 
= 320

Answer(s): 320
