PSLE A group of pupils was asked to choose one rice set from egg, vegetarian, turkey and beef. The table represents the pupils' choices. The pupils' choices were also represented by a bar graph but the names of the rice sets were not shown. What was the total number of pupils who chose turkey and egg rice sets?
Rice Sets |
Pupils |
Egg |
35% |
Vegetarian |
15% |
Turkey |
10% |
Beef |
40% |
Number of pupils who chose turkey rice sets is the least. So it is represented by the shortest bar.
Number of pupils who chose turkey rice sets = 20
10% of pupils = 20
1% of pupils = 20 ÷ 10 = 2
Percent of pupils who chose egg rice sets = 35%
Percent of pupils who chose vegetarian rice sets = 15%
Percent of pupils who chose egg and vegetarian rice sets
= 35% + 15%
= 50%
Total number of pupils who chose turkey and egg rice sets
= 50 x 2
= 100
Answer(s): 100
