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

Burgers	Pupils
Tuna	30%
Mutton	10%
Vegetarian	25%
Chicken	35%

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

Number of pupils who chose mutton burgers = 30

10% of pupils = 30

1% of pupils = 30 ÷ 10 = 3

Percent of pupils who chose vegetarian burgers = 25%
Percent of pupils who chose tuna burgers = 30%

Percent of pupils who chose vegetarian and tuna burgers
= 25% + 30%
= 55%

Total number of pupils who chose mutton and chicken burgers
= 55 x 3
= 165

Answer(s): 165
