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

Burgers	Pupils
Egg	5%
Hotdog	35%
Vegetarian	50%
Mutton	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 egg burgers = 5%
Percent of pupils who chose vegetarian burgers = 50%

Percent of pupils who chose egg and vegetarian burgers
= 5% + 50%
= 55%

Total number of pupils who chose egg and vegetarian burgers
= 55 x 3
= 165

Answer(s): 165
