PSLE
A group of pupils was asked to choose one rice set from hotdog, chicken, tuna 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 hotdog and tuna rice sets?

Rice Sets	Pupils
Hotdog	5%
Chicken	50%
Tuna	10%
Beef	35%

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

Number of pupils who chose hotdog rice sets = 15

5% of pupils = 15

1% of pupils = 15 ÷ 5 = 3

Percent of pupils who chose hotdog rice sets = 5%
Percent of pupils who chose tuna rice sets = 10%

Percent of pupils who chose hotdog and tuna rice sets
= 5% + 10%
= 15%

Total number of pupils who chose hotdog and tuna rice sets
= 15 x 3
= 45

Answer(s): 45
