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

Noodle Sets	Pupils
Egg	15%
Turkey	30%
Hotdog	30%
Mutton	25%

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

Number of pupils who chose egg noodle sets = 30

15% of pupils = 30

1% of pupils = 30 ÷ 15 = 2

Percent of pupils who chose egg noodle sets = 15%
Percent of pupils who chose hotdog noodle sets = 30%

Percent of pupils who chose egg and hotdog noodle sets
= 15% + 30%
= 45%

Total number of pupils who chose egg and hotdog noodle sets
= 45 x 2
= 90

Answer(s): 90
