PSLE
A group of pupils was asked to choose one spaghetti set from egg, beef, turkey and mutton. 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 turkey and egg spaghetti sets?

Spaghetti Sets	Pupils
Egg	35%
Beef	45%
Turkey	5%
Mutton	15%

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

Number of pupils who chose turkey spaghetti sets = 10

5% of pupils = 10

1% of pupils = 10 ÷ 5 = 2

Percent of pupils who chose egg spaghetti sets = 35%
Percent of pupils who chose beef spaghetti sets = 45%

Percent of pupils who chose egg and beef spaghetti sets
= 35% + 45%
= 80%

Total number of pupils who chose turkey and egg spaghetti sets
= 80 x 2 
= 160

Answer(s): 160
