PSLE A group of pupils was asked to choose one noodle set from mutton, beef, vegetarian and tuna. 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 vegetarian and mutton noodle sets?
Noodle Sets |
Pupils |
Mutton |
15% |
Beef |
45% |
Vegetarian |
5% |
Tuna |
35% |
Number of pupils who chose vegetarian noodle sets is the least. So it is represented by the shortest bar.
Number of pupils who chose vegetarian noodle sets = 10
5% of pupils = 10
1% of pupils = 10 ÷ 5 = 2
Percent of pupils who chose mutton noodle sets = 15%
Percent of pupils who chose beef noodle sets = 45%
Percent of pupils who chose mutton and beef noodle sets
= 15% + 45%
= 60%
Total number of pupils who chose vegetarian and mutton noodle sets
= 60 x 2
= 120
Answer(s): 120
