PSLE
A group of students was asked to choose one sandwich from beef, turkey, mutton and chicken. 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 mutton and beef sandwiches?

Sandwiches	Students
Beef	30%
Turkey	35%
Mutton	5%
Chicken	30%

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

Number of students who chose mutton sandwiches = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose beef sandwiches = 30%
Percent of students who chose turkey sandwiches = 35%

Percent of students who chose beef and turkey sandwiches
= 30% + 35%
= 65%

Total number of students who chose mutton and beef sandwiches
= 65 x 2 
= 130

Answer(s): 130
