PSLE
A group of students was asked to choose one burger from chicken, mutton, egg and vegetarian. 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 chicken burgers?

Burgers	Students
Chicken	20%
Mutton	10%
Egg	30%
Vegetarian	40%

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

Number of students who chose mutton burgers = 30

10% of students = 30

1% of students = 30 ÷ 10 = 3

Percent of students who chose egg burgers = 30%
Percent of students who chose chicken burgers = 20%

Percent of students who chose egg and chicken burgers
= 30% + 20%
= 50%

Total number of students who chose mutton and vegetarian burgers
= 50 x 3
= 150

Answer(s): 150
