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

Burgers	Pupils
Egg	40%
Hotdog	30%
Vegetarian	5%
Beef	25%

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

Number of pupils who chose vegetarian burgers = 10

5% of pupils = 10

1% of pupils = 10 ÷ 5 = 2

Percent of pupils who chose egg burgers = 40%
Percent of pupils who chose hotdog burgers = 30%

Percent of pupils who chose egg and hotdog burgers
= 40% + 30%
= 70%

Total number of pupils who chose vegetarian and egg burgers
= 70 x 2 
= 140

Answer(s): 140
