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

Tacos	Pupils
Tuna	35%
Chicken	10%
Turkey	5%
Egg	50%

Number of pupils who chose turkey tacos is the least. So it is represented by the shortest bar.

Number of pupils who chose turkey tacos = 20

5% of pupils = 20

1% of pupils = 20 ÷ 5 = 4

Percent of pupils who chose tuna tacos = 35%
Percent of pupils who chose chicken tacos = 10%

Percent of pupils who chose tuna and chicken tacos
= 35% + 10%
= 45%

Total number of pupils who chose turkey and tuna tacos
= 45 x 4 
= 180

Answer(s): 180
