PSLE A group of pupils was asked to choose one noodle set from beef, chicken, egg and vegetarian. 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 beef noodle sets?
Noodle Sets |
Pupils |
Beef |
35% |
Chicken |
15% |
Egg |
30% |
Vegetarian |
20% |
Number of pupils who chose chicken noodle sets is the least. So it is represented by the shortest bar.
Number of pupils who chose chicken noodle sets = 30
15% of pupils = 30
1% of pupils = 30 ÷ 15 = 2
Percent of pupils who chose egg noodle sets = 30%
Percent of pupils who chose beef noodle sets = 35%
Percent of pupils who chose egg and beef noodle sets
= 30% + 35%
= 65%
Total number of pupils who chose chicken and vegetarian noodle sets
= 65 x 2
= 130
Answer(s): 130
