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

Spaghetti Sets	Pupils
Beef	20%
Vegetarian	45%
Turkey	10%
Tuna	25%

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 = 30

10% of pupils = 30

1% of pupils = 30 ÷ 10 = 3

Percent of pupils who chose beef spaghetti sets = 20%
Percent of pupils who chose vegetarian spaghetti sets = 45%

Percent of pupils who chose beef and vegetarian spaghetti sets
= 20% + 45%
= 65%

Total number of pupils who chose turkey and beef spaghetti sets
= 65 x 3 
= 195

Answer(s): 195
