PSLE
A group of students was asked to choose one rice set from chicken, mutton, tuna and egg. 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 chicken and tuna rice sets?

Rice Sets	Students
Chicken	5%
Mutton	40%
Tuna	10%
Egg	45%

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

Number of students who chose chicken rice sets = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose chicken rice sets = 5%
Percent of students who chose tuna rice sets = 10%

Percent of students who chose chicken and tuna rice sets
= 5% + 10%
= 15%

Total number of students who chose chicken and tuna rice sets
= 15 x 2
= 30

Answer(s): 30
