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

Burgers	Pupils
Turkey	70%
Chicken	5%
Beef	10%
Vegetarian	15%

Number of pupils who chose chicken burgers is the least. So it is represented by the shortest bar.

Number of pupils who chose chicken burgers = 20

5% of pupils = 20

1% of pupils = 20 ÷ 5 = 4

Percent of pupils who chose beef burgers = 10%
Percent of pupils who chose turkey burgers = 70%

Percent of pupils who chose beef and turkey burgers
= 10% + 70%
= 80%

Total number of pupils who chose chicken and vegetarian burgers
= 80 x 4
= 320

Answer(s): 320
