PSLE
A group of students was asked to choose one taco from chicken, hotdog, tuna and beef. 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 tuna and chicken tacos?

Tacos	Students
Chicken	45%
Hotdog	25%
Tuna	5%
Beef	25%

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

Number of students who chose tuna tacos = 15

5% of students = 15

1% of students = 15 ÷ 5 = 3

Percent of students who chose chicken tacos = 45%
Percent of students who chose hotdog tacos = 25%

Percent of students who chose chicken and hotdog tacos
= 45% + 25%
= 70%

Total number of students who chose tuna and chicken tacos
= 70 x 3 
= 210

Answer(s): 210
