PSLE
A group of pupils was asked to choose one taco from turkey, tuna, mutton and chicken. 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 mutton and turkey tacos?

Tacos	Pupils
Turkey	30%
Tuna	30%
Mutton	5%
Chicken	35%

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

Number of pupils who chose mutton tacos = 15

5% of pupils = 15

1% of pupils = 15 ÷ 5 = 3

Percent of pupils who chose turkey tacos = 30%
Percent of pupils who chose tuna tacos = 30%

Percent of pupils who chose turkey and tuna tacos
= 30% + 30%
= 60%

Total number of pupils who chose mutton and turkey tacos
= 60 x 3 
= 180

Answer(s): 180
