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

Tacos	Students
Beef	10%
Egg	40%
Tuna	30%
Hotdog	20%

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

Number of students who chose beef tacos = 40

10% of students = 40

1% of students = 40 ÷ 10 = 4

Percent of students who chose beef tacos = 10%
Percent of students who chose tuna tacos = 30%

Percent of students who chose beef and tuna tacos
= 10% + 30%
= 40%

Total number of students who chose beef and tuna tacos
= 40 x 4
= 160

Answer(s): 160
