PSLE
A group of pupils was asked to choose one spaghetti set from chicken, tuna, egg and hotdog. The table represents the pupils' choices. The pupils' choices were also represented by a bar graph but the names of the spaghetti sets were not shown. What was the total number of pupils who chose chicken and egg spaghetti sets?

Spaghetti Sets	Pupils
Chicken	5%
Tuna	15%
Egg	15%
Hotdog	65%

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

Number of pupils who chose chicken spaghetti sets = 15

5% of pupils = 15

1% of pupils = 15 ÷ 5 = 3

Percent of pupils who chose chicken spaghetti sets = 5%
Percent of pupils who chose egg spaghetti sets = 15%

Percent of pupils who chose chicken and egg spaghetti sets
= 5% + 15%
= 20%

Total number of pupils who chose chicken and egg spaghetti sets
= 20 x 3
= 60

Answer(s): 60
