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

Tacos	Pupils
Vegetarian	5%
Mutton	20%
Beef	15%
Tuna	60%

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

Number of pupils who chose vegetarian tacos = 10

5% of pupils = 10

1% of pupils = 10 ÷ 5 = 2

Percent of pupils who chose vegetarian tacos = 5%
Percent of pupils who chose beef tacos = 15%

Percent of pupils who chose vegetarian and beef tacos
= 5% + 15%
= 20%

Total number of pupils who chose vegetarian and beef tacos
= 20 x 2
= 40

Answer(s): 40
