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

Tacos	Pupils
Tuna	25%
Egg	30%
Beef	5%
Turkey	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 = 15

5% of pupils = 15

1% of pupils = 15 ÷ 5 = 3

Percent of pupils who chose tuna tacos = 25%
Percent of pupils who chose egg tacos = 30%

Percent of pupils who chose tuna and egg tacos
= 25% + 30%
= 55%

Total number of pupils who chose beef and tuna tacos
= 55 x 3 
= 165

Answer(s): 165
