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

Sandwiches	Students
Mutton	25%
Turkey	5%
Hotdog	50%
Beef	20%

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

Number of students who chose turkey sandwiches = 10

5% of students = 10

1% of students = 10 ÷ 5 = 2

Percent of students who chose hotdog sandwiches = 50%
Percent of students who chose mutton sandwiches = 25%

Percent of students who chose hotdog and mutton sandwiches
= 50% + 25%
= 75%

Total number of students who chose turkey and beef sandwiches
= 75 x 2
= 150

Answer(s): 150
