PSLE
A group of pupils was asked to choose one taco from hotdog, turkey, beef 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 beef and hotdog tacos?

Tacos	Pupils
Hotdog	10%
Turkey	45%
Beef	5%
Chicken	40%

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

Number of pupils who chose beef tacos = 10

5% of pupils = 10

1% of pupils = 10 ÷ 5 = 2

Percent of pupils who chose hotdog tacos = 10%
Percent of pupils who chose turkey tacos = 45%

Percent of pupils who chose hotdog and turkey tacos
= 10% + 45%
= 55%

Total number of pupils who chose beef and hotdog tacos
= 55 x 2 
= 110

Answer(s): 110
