PSLE
A group of pupils was asked to choose one rice set from chicken, 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 rice sets were not shown. What was the total number of pupils who chose chicken and vegetarian rice sets?

Rice Sets	Pupils
Chicken	10%
Hotdog	35%
Vegetarian	35%
Beef	20%

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

Number of pupils who chose chicken rice sets = 20

10% of pupils = 20

1% of pupils = 20 ÷ 10 = 2

Percent of pupils who chose chicken rice sets = 10%
Percent of pupils who chose vegetarian rice sets = 35%

Percent of pupils who chose chicken and vegetarian rice sets
= 10% + 35%
= 45%

Total number of pupils who chose chicken and vegetarian rice sets
= 45 x 2
= 90

Answer(s): 90
