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

Sandwiches	Students
Egg	20%
Beef	5%
Chicken	35%
Tuna	40%

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

Number of students who chose beef sandwiches = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose chicken sandwiches = 35%
Percent of students who chose egg sandwiches = 20%

Percent of students who chose chicken and egg sandwiches
= 35% + 20%
= 55%

Total number of students who chose beef and tuna sandwiches
= 55 x 2
= 110

Answer(s): 110
