PSLE
A group of pupils was asked to choose one burger from chicken, egg, tuna and hotdog. 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 tuna and chicken burgers?

Burgers	Pupils
Chicken	75%
Egg	5%
Tuna	10%
Hotdog	10%

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

Number of pupils who chose egg burgers = 15

5% of pupils = 15

1% of pupils = 15 ÷ 5 = 3

Percent of pupils who chose tuna burgers = 10%
Percent of pupils who chose chicken burgers = 75%

Percent of pupils who chose tuna and chicken burgers
= 10% + 75%
= 85%

Total number of pupils who chose egg and hotdog burgers
= 85 x 3
= 255

Answer(s): 255
